E. Checkout Procedure
Before any system of gas piping is finally put into service, it shall be carefully
tested to assure that it is “gas-tight”, as indicated in the General Gas Piping
Requirements section of this manual.
NOTICE: All controls on the unit should be checked for proper functioning
prior to the qualified service personnel leaving the job site. Specifically the
following should be checked:
1. With heating system in normal heating operation, check to make certain
blower will start and stop automatically under control of integrated furnace
control.
2. Check safety limit control as follows:
a. Shut off incoming power.
b. Block return air opening or disconnect blower motor leads.
c. Restore power to appliance.
d. In the heating mode, set the thermostat above room temperature
producing “a call for heat”.
e. When high air temperatures are reached within the furnace, the high limit
control should act to shutdown the main burners.
f. Shut off the electrical power.
IMPORTANT: Remove blockage or reconnect blower motor and
restore power.
3. Make certain the thermostat will automatically start and stop the appliance.
4. Block the vent terminal outlet gradually with a flat piece of metal, until the
pressure switch functions shutting off the main burners.
IMPORTANT: Remove flue blockage when done.
NOTICE: Heat exchanger oil will burn off on initial firing creating an
unpleasant odor. To prevent this odor from occurring more than once, it is
suggested the furnace be allowed to run for 30 minutes, or until odor has
dissipated.
