Thermostat is now in standby mode waiting for the next “Call for Heat”. WARNING To minimize the possibility of serious personal injury, fire or damage to your appliance, never violate the following safety rules. DO NOT Do not use this appliance if any part of it has been under water.
1.8 REMOVAL OF EXISTING APPLIANCE When an existing appliance is removed from a common venting system, the common venting system is likely to be too large for proper venting of the appliances remaining connected to it. At the time of removal of an existing appliance, the following steps must be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.
• • • • • • The appliance must be installed so that the ignition system components are protected from water (dripping, spraying, etc.) during appliance operation and service (circulator replacement, control replacement, etc.) Appliances located in a residential garage and in adjacent spaces that open to the garage and are not part of the living space of a dwelling unit must be installed so that all burners and burner ignition devices have a minimum clearance of not less than 18" (46cm) above the floor.

Table 6: Maximum Flue Temperature for Various Vent Materials Vent Material Maximum Flue Temperature [oF] PVC 149 CPVC 194 PPE AL29-4C 230 1) 300+, limited only by rating of seals 300+, limited only by rating of seals 316L Stainless Steel o Stack temperature is typically between 15-30 F above inlet water temperature depending on model size and firing rate.
Air inlet point for multiple boiler air inlets must be provided with an exterior opening which has a free area equal to or greater than the total area of all air inlet pipes connected to the common air inlet. This exterior opening for combustion air must connect directly to the outdoors. The total length of the combined air inlet pipe must not exceed a maximum of 100 equivalent feet (30.5m).
Location of a Sidewall Air Inlet Cap 1) Total length of piping for air inlet must not exceed the limits stated in Table 7. 2) Point of termination for the sidewall air inlet cap must be located a minimum of 12 inches (0.30m) away from the flue gas termination, but never above. 3) Air piping must terminate in a down-turned elbow to avoid recirculation of flue products into the inlet air stream. 4) DO NOT terminate closer than 4 feet (1.
Location of a Vertical Air Inlet Opening 1) The total length of piping for inlet air must not exceed the limits given in Table 7. o 2) The air inlet consists of two 90 elbows installed at the point of termination for the vertical air inlet pipe. o o A 90 elbow and a 90 street elbow may be used to make this assembly. If a straight piece of pipe is used between the two elbows, it should not exceed 6” (0.15m) in length. The air inlet opening must be at least 1 foot below the vent opening.
PART 3 GAS CONNECTION Verify that the appliance is supplied with the type of gas specified on the rating plate. Consult factory for installations at high altitude. 3.1 • • • • • • The appliance and its individual gas shut-off valve must be disconnected from the supply piping when pressure testing the gas supply piping at pressures above ½ PSI Table 9: Gas Pressures at Inlet to Appliance GAS CONNECTION Safe operation of unit requires properly sized gas supply piping. See gas line sizing data.
IMPORTANT Upon completion of initial installation or following any repair work on the gas system, leak test all gas connections with a soap solution while the main burner is firing. Immediately repair any leak found in the gas train or related components. DO NOT operate an appliance with a leak in the gas train, valves or related gas piping. 3.
This appliance uses a single cylindrical burner installed horizontally into the cavity located in the center of the heat exchanger. A unique burner is used for each one of the DynaMax HS models. Burners may NOT be interchanged between different Btu/hr input models. The burner consists of a round mounting flange welded to a ported stainless steel mixing tube. This stainless steel tube is covered with a close fitting, knitted stainless steel metal fiber alloy material that forms the burner outer surface.

PART 9 MAINTENANCE 9.3 CLEANING BOILER HEAT EXCHANGER Figure 32: Heat Exchanger & Burner Assembly CAUTION It is important that all gas appliances be serviced by a qualified technician trained by Camus Hydronics. It is in your own interest and that of safety to ensure that all local codes, and all the “NOTES” and “WARNINGS” in this manual are complied with.
12) Brush the heat exchanger with a nylon bristle brush. DO NOT use a metal brush. Re-vacuum the heat exchanger. Many jurisdictions will require the acidic condensate to be neutralized before it can be placed in a drain system. • 13) Finish cleaning by wiping down the boiler heating surfaces with a clean, damp cloth. 14) Rinse out any additional debris with a low pressure water supply. Start rinsing from the rear of the heat exchanger and slowly working your way towards the front of the heat exchanger.
on an annual basis. An appliance installed in a dust or dirt contaminated environment will require inspection and cleaning on a more frequent schedule. The fan assisted combustion process may force airborne dust and dirt contaminants, contained in the combustion air, into the burner. With sustained operation, non-combustible contaminants may reduce burner port area, reduce burner input or cause non-warrantable damage to the burner. Never operate this appliance during construction.
9.10 GAS VALVE VOLTAGE This appliance uses a transformer to supply a 24 volt signal to the Honeywell SOLA. The voltage on the secondary side should be 24 to 28VAC when measured with a voltmeter. A secondary voltage of 21VAC or less supplied to 24VAC components may cause operational problems. 9.11 • • • • • FREEZE PROTECTION FOR INDOOR & OUTDOOR INSTALLATIONS Installations are not recommended in areas where the danger of freezing exists.
PART 10 INSTALLATIONS WARNING Before starting the boiler, smell near the floor and around the boiler for any gas odours or any unusual odour. Remove the stainless steel jacket and smell the interior of the boiler. If there is any sign of a gas leak, do not proceed with startup. Repair all the leaks before attempting to start the boiler. WARNING Propane boilers ONLY – Your local propane supplier adds an odorant to the propane gas to allow for propane gas leak detection.
10.7 a) Boiler Set-Up SUMMARY 1) Typical Boiler Installations General Plumbing Rules 1) Check all local codes. 2) For serviceability, always install unions. 3) Always pipe pressure relief valve to an open drain. 4) Locate system air vents at highest points of system. 5) Expansion tank must be installed near the boiler and on the suction side of the system pump. 6) Support all water piping. 7) Place drip pan underneath boiler.
3) 4) 5) 6) 10.10 1) 2) 3) 4) 5) For example in some cases it may be the bath tub and in some cases it may be the clothes washer. Allow the DynaMax HS to fire up and reach full fire under maximum hot water load demand conditions. Observe the outlet water temperature and close the tuning valve gradually as outlet temperature starts to drop. Allow the system to reach equilibrium between adjustments to the tuning valve.
10.11 LEAD LAG SETUP The following components are needed for a Lead Lag setup 1) 10kΩ System Sensor Turn off all the boilers before beginning the setup process. To setup the DynaMax HS lead lag system follow the instructions: System Sensor Insert the supplied 10kΩ system sensor into the building loop. The wires coming out of the system sensor should be connected to pin#5 and #6 of the green DynaMax HS terminal board. NOTE The use of a system sensor is required in lead lag operation.
10.12 LOCAL/REMOTE SWITCH The local remote switch mounted on the terminal board is designed to generate a call for heat either relying on an external contact closure (Remote) or enabling the boiler locally (local). When Remote is selected via the SPDT switch the Remote Operator contacts on the terminal board must be closed to initiate a call for heat. When Local is selected via the SPDT switch a constant call for heat is generated which will enable the boiler to proceed to a trial for ignition.
