Years of engineering have gone into the development of these fine products and only top quality components and materials are used throughout. Each machine is carefully tested and inspected before leaving our plant to ensure years of dependable service. The rest is up to you.
9 HIGH LIMIT TEMPERATURE CONTROL The water heater is equipped with a “high limit control” thermostat present at 220 F. It shuts down the burner in the event of excessive outlet temperature caused by insufficient water flow through the heater coil. This control can be adjusted to desired temperature up to but not exceeding 220 F. PRESSURE SWITCH A pressure switch is installed on the high pressure pump to prevent burner operation in the absence of water flow.
10 PROPANE For stationary installations, run a minimum 3/4 IPS supply line as above. For portable applications, a hose and regulator assembly is included with the optional portability kit. This includes a P01 tank connector, single stage regulator and an approved supply hose for connection to a combination gas valve. Obtain one or more 100 lb. propane tank (s) and locate near the heater.
11 CAUTION: If the heater is left unused for extended periods during sub-zero weather, a column of freezing air will build up in the venting system. If the building has a negative pressure condition, some of the freezing air will be drawn over the draft hood, spilling onto the heating coil which will eventually cause it to freeze and rupture. Have an installer ensure that correct draft conditions are maintained to prevent this costly occurrence.
12 OPERATING INSTRUCTIONS TO OPERATE MAIN BURNER Be sure water is flowing through water heater coil before turning on burner switch. Start the pumping unit involved until a steady stream of water is flowing from the spray gun. Turn burner switch to “On” position. Burner will ignite and remain in operation as long as there is sufficient water flow to satisfy the pressure switch and temperature limit control. To shut off main burner, turn burner switch to “Off”.
13 BURNER MAINTENANCE WARNING: Repair of the burner is to be done by authorized and trained burner professionals only. Due to periodic condensation dripping down onto the burner a scale build up may eventually occur in the burner jet orifices. BURNER REMOVAL Shut off the gas supply line to the water heater. Disconnect ¾ pipe union in burner valve train. Remove the two burner retaining nuts. Turn gas cock knob on combination gas valve to “Off” position. Remove Boiler Assembly from frame.
