HOSE ASSEMBLIES
The hose assemblies shall be visually inspected prior to each use of the heater. If it is evident there is excessive
abrasion or wear, or the hose is cut, it must be replaced prior to the heater being put into operation. The replacement
hose assembly shall be that specified by the manufacturer.
HIGH LIMIT SWITCH
The limit switch should be checked every heating season to ensure the burner will shutdown if temperature exceeds
250 F (US)/290 F (CA). This can be accomplished by restricting the air flow through the unit. After tests are complete,
remove restrictors as both 12” ducts must be open for proper operation.
FAN SWITCH
The fan switch has been selected to allow for preheating of the heat exchanger to ensure that only heated air is
allowed to enter the space. Upon satisfying the need for heat, the fan switch will continue to run the supply fan until
the heat exchanger has cooled sufficiently. This feature will help prolong the life of the heat exchanger. The fan switch
(when in automatic mode) must be replaced if the fan motor does not shut off after the heat exchanger has cooled
down.
There is a manual fan switch for continual air located on control panel.
ELECTRICAL
Ensure all conduit (BX) connectors are tight. Open plug in cord and check connections tight and no frayed wires
exposed. Check inside connections in control box to ensure good connections.
FAN
Check for dust or dirt build up on blades. Check for tightness of the set screw. Run heater to check for fan vibration.
Replace fan blade if vibration is noticeable. The flow of combustion and ventilation air must not be obstructed. Be
sure to check the fan assembly and ensure that the motor and blade are operating properly.
MOTOR
No lubrication is necessary since the bearings are the sealed type. Clean motor of existing dust or dirt.
NOTE: FLOW OF COMBUSTION AND VENTILATION AIR CANNOT BE OBSTRUCTED
HEAT EXCHANGER
If a smoky condition continues even after adjusting the air band assembly, the heat exchanger should be thoroughly
cleaned.
AFTER INSPECTION, A COMPLETE COMBUSTION TEST MUST BE PEFORMED AFTER EACH ANNUAL
SERVICE OF THE UNIT TO MAINTAIN OPTIMUM PERFORMANCE AND RELIABILITY.
WARNING: TURN OFF THE FUEL SUPPLIES AND POWER BEFORE PERFORMING SERVICE
WORK. THE 120 VOLT CIRCUIT IS A POTENTIAL ELECTROCUTION HAZARD.
THE WRAP-AROUND EXCHANGER CAN NOW BE CLEANED ENTIRELY FROM THE CLEAN-OUT PORT AND
THE FLUE PIPE CONNECTION.
HEAT EXCHANGER CLEANING PROCEDURE
1.) REMOVE EASY ACCESS PANEL LOCATED ON TOP HEATER BOX PANEL
2.) REMOVE EASY ACCESS PANEL LOCATED ON TOPSIDE OF HEAT EXCHANGER
3.) SHOVE FLEXIBLE BRUSH VIA ACCESS PANEL AND CLEAN THOROUGHLY
4.) SHOVE FLEXIBLE VACUUM VIA ACCESS PANEL AND VACUUM THOROUGHLY
