QB Oil Fired Water Heaters • Rev. 4/13/2016
TO CHECK HEATER COILS FOR LEAKS
Start pumping unit and allow it to run for a few minutes with burner turned off. Check burner
compartment with a trouble light or flash light. If no leaks are visible, this will confirm that
occasional water dripping from the coil is due to condensation of the flue gases, when burner is
firing.
WINTER PUMP/ COIL PROTECTION
The following procedure MUST be used when the pressure washing unit is
stored at temperatures below freezing.
1. All water must be drained or blown (via compressed air) from system. Connect a short piece of
male fitted ½” garden type hose on to the water inlet on the pump.
2. Place open end of hose into a wide mouthed container of full strength, winter rated, vehicle
windshield washing fluid or Anti-Freeze,
RATED FOR MINIMUM -40°C
.
3. Connect the pressure wand assembly.
4. Start engine and engage trigger on pressure gun. Operate system until fluid runs the same color as
windshield washing fluid. Your machine is now prepared for storage.
5. Disconnect fluid supply, blow out with compressed air, and cap end.
GENERAL MAINTENANCE
Burner Maintenance
NOTE: Repair of the burner is to be done by authorized and trained burner professionals
only.
The oil filter cartridge should be replaced every year to prevent fuel contamination and plugging of
fuel pump and nozzle of oi burner. The nozzle should also be replaced at least once every year or
twice if used daily and if poor combustion begins to occur. See included burner manual for more
information on the burner.
Final adjustments to burner include fuel pressure adjustment for controlling water temperature
(tighten fuel pressure adjustment screw slightly to increase desired output temperature) and air band
adjustment for combustion efficiency. A combustion test kit should be used for these final
adjustments. Check SPECIFICATIONS chart (page 7) for the burner oil pressure corresponding to
your model and be sure not to exceed this pressure. See included burner manual for more
information and a parts break down of the burner.
