WARNING
This furnace is designed to operate with the ALL 20 flue-pipe baffles
correctly installed. The maximum normal flue temperature is 125
Degrees °F after 10 minutes of operation at a maxim um distance of 18
inches from the breach of the unit.
IT IS MANDATORY TO MEASURE THE FLUE-PIPE TEMPERATURE,
as part of the combustion test, UPON INSTALLATION. This
measurement must be taken as close as possible to the breech of the
unit, through the plastic flue pipe downstream of the black rubber
connector. To do this check, simply make a small hole (large enough
for your temperature probe) in the flue pipe. Upon completion of the
test, cover the hole with HVAC aluminum tape.
If the temperature is OVER 125 Degrees °F:
1. Check that ALL 20 baffles are in place. To do this you must
remove the black plastic collector pan as described in section 7.1;
2. Check that the correct nozzle is installed in the burner;
3. Check that you have the correct burner pump pressure;
4. Make sure the blower door is closed during operation;
5. Make sure that the condensate disposal system is not blocked. If
that is the case, unblock.
IF THE UNIT IS STILL OPERATING OVER 125 DEGREES F AFTER
THESE CHECKS, CALL GRANBY FURNACES INC. “CUSTOMER
CARE”.
PROLONGED OPERATION OVER 125 DEGREES ºF COULD LEAD
TO UNSAFE OPERATION, PREMATURE FAILURE OF THE
EQUIPMENT AND BODILY HARM.
