diesel www.dieselheat.com.au Installation Guidelines Diesel heat is providing this installation manual to help make sure your installation is successful. Please read this guide carefully as many product issues can result from improperly performed installations. We can't take responsibility for performance loss, product damage or failure that has resulted from poor installation practices or a failure to follow recommended guidelines.

Operating the unit with inadequate inlet air will cause suiting up and almost immediate need for service. eo For marine installations, when deciding where to locate the furnace, always take into account that the maximum allowable length of the exhaust is 2m.

Coolant Fum ace Location Options Caravan/RV ® On the side of the hot water service tank (default) this gives the most compact install with the components close together. eo Externally in a box (which must be ventilated when the fum ace is running). # Under the chassis on a vehicle.
diesels www.dieselheat.com.au Hot Water Service Tank Mounting o The supplied mounting plate can be fixed to the back or the base of the hot water service tank. o Install the plate with the 4 supplied countersunk screws. # Note that the mounting plate is asymmetrical; the longer side is designed to go under/behind the plumbing.
diesel www.dieselheat.com.au Set Up The Tank The tank is shipped with the tempering valve installed and these connections are pressure tested prior to shipping. dea We do not recommend moving or adjusting the tempering valve as the connections require special sealant and tightening. All connections for coolant on the tank need to be sealed with either thread tape or Maalox 58-11 to ensure there are no coolant leaks.
@ diesels www.dieselheat.com.au Hot water only installations. For hot water only installations, connectors 1 and § should be blocked with the supplied plugs. However, the bypass hole blocking ring should not be installed. Installations with 1 fan head located at or below 0.5m above the top of the coolant tank. For installations with only 1 fan head located within 1.5m of the tank at or below 0.
diesels www.dieselheat.com.au Installations with multiple fan heads, fan heads located up to 1m above the level of the tank or where the fan head is more than 1.5m from the tank. For these installations, ports 1 and & should have hoses tails installed and the bypass hole blocking ring must be Installed. This prevents coolant passing back into the tank and significantly increases the available pump pressure to drive circulation of the coolant.

diesel www.dieselheat.com.au Plumbing the Coolant Hoses The hot water service to fan heating head plumbing should be done with 16mm ID rubber hoses and secured with hose clamps. Fan head installation kits from Diesel heat contain 2m of the necessary hose and all other hose tails and clamps. If remote-mounting the furnace, the furnace to hot water service tank plumbing should be done with rubber or silicone hoses of 18-20mm ID and secured with quality hose clamps.
diesel www.dieselheat.com.au Fan Heater Installation The hoses connecting the cabin fan heater are connected directly to the DH15/DH30 tank ports. The cabin fan heaters should be plumbed with 16mm hose for short runs (less than 2m) or 16mm insulated PEX for longer runs. To mount the cabin heater: * Remove the front face of the heater and measure the outlet surface area. Cut the appropriate hole in the board. * Sandwich the kick board between the face and the main heater housing.
diesels www.dieselheat.com.au Controlling The Air Temperature Temperature control can be achieved via 3 methods. The first method is via an inline valve with the coolant return line from the fan head. Partially closing the valve will restrict the coolant circulation and reduce the heat given off by the fan head. The VA200 fan : head has the valve built in, while other fan heads can have a ball valve installed behind them.
@ diesel www.dieselheat.com.au Tempering Valve Controlling Water Temperature ‘When the system has been muted on and has warmed up, the water coming straight from the DH15/DH30 hot water service will be approximately 70-75 degrees. The tempering valve not only controls the outlet temperature but will increase the usable hot water capacity. The volume of coolant at 70-75 degrees is directly related to how much hot water is available at 45-50 degrees.
diesel www.dieselheat.com.au Fuel System Note: The Cyberspace fuel pump needs to be orientated differently from the Belief fuel pump. Please follow the Instructions below to ensure your pump Is Installed the correct way. Cyberspace Fuel System Follow the Cyberspace HSE HS3 technical manual for fuel system installation. Ensure the pump is installed with the comet orientation. The outlet is on the opposite side to the power cable.
diesel www.dieselheat.com.au Fuel Source The DH15/DH30 can be connected to an auxiliary fuel tank, to a day tank or to a connection point on the main fuel system or generator fuel system. When connecting to main fuel systems in boats or motor homes, it is important to ensure that the fuel take off point is not pressurized (downstream of any feed pumps) and that there are no opportunities for air to enter the fuel lines.
diesel www.dieselheat.com.au RV Exhaust The exhaust system on an RV consists of 2 lengths of exhaust and a muffler. The exhaust should be installed in a manner that ensures it cannot dislodge or come into contact with any electrical wiring, water pipes, enc, as it is hot enough to melt plastics. The exhaust should have a length of pipe before the muffler and generally at least 30cm of pipe after the muffler, as this helps to manage noise.
diesel www.dieselheat.com.au Marine Exhaust Always use high-quality marine stainless steel exhaust systems and clamps to ensure no exhaust gasses are vented Inside the boat. The total maximum length of the marine exhaust is 2m. Always install the exhaust with a goose neck on the inside of a hull fitting to prevent water washing back into the exhaust system. Note: The exhaust system reaches temperatures of up to 300°C.
diesel www.dieselheat.com.au Combustion Air The DH15/DH30 ships with the fum ace combustion air inlet pipe and combustion silencer per-installed. For marine applications or instances in RVs where the fum ace is installed inside a locker or cupboard, it is acceptable to install the combustion air inlet inside the engine room or locker. For vehicles that will be operating in dusty conditions, it is not recommended to install the combustion air inlet outside the vehicle.
diesel www.dieselheat.com.au Commissioning It is a time consuming and messy operation to rectify any bad joints or leaks after the system is filled with coolant. The coolant system operates at approximately 5-psi, s0 check that all hose connections are secure and all hoses are kink free before filling the system with coolant. ‘When the system is 100% installed, insert the fuses in the power line and power up the fum ace. Coolant Pump Priming Remove the radiator cap on the DH15/DH30 hot water service.
diesel www.dieselheat.com.au Initial Startup Once the coolant pump is primed, leave the switch on and the fum ace will attempt to start. The furnace will not start until the fuel pump and fuel line have primed. A fum ace start process involves 2 separate start attempts and takes approximately 6 minutes. During each start attempt, the coolant pump runs, the combustion fan revs up and down and the fuel pump attempts to pump fuel.
diesel www.dieselheat.com.au Coolant Fum ace Operation Tum on the fum ace with the on\off switch. After approximately 3 seconds, the coolant circulating pump will come on. The glow pin and fuel pump will then come on and the fum ace will start its combustion cycle. Once the furnace obtains full combustion, it will continue to produce heat on full power until the coolant temperature reaches 70°C. This will take approximately 8 minutes, depending on the ambient temperature.
diesel www.dieselheat.com.au Commissioning Troubleshooting Problem Things to Check On Initial switch on, fum ace does nothing. Check fuel pump connection wires are properly Inserted Into connector and connector is properly plugged into the pump. Check coolant pump wires are properly connected. Check power supply and fuses. Check furnace is wired directly to batteries. Check power wiring polarity red (inside black sleeve is positive, brown is negative). Fum ace tries to start but doesn't start.
diesel www.dieselheat.com.au System heats up but fan heads do not get hot. Check fan head shut off valves are open. If using a valved bypass valve, ensure the bypass valve is partially closed. If using a valveless bypass valve, check the bypass valve is on the same level as the fan head. Check tank plumbing and bypass arrangements are in accordance with diagrams in these instructions. Fan heads get hot but do not blow hot air. Check fans are wired with correct polarity.
