3.9 BLOWER SETTINGS
Ensure power is off when adjusting blower setting
. For heating, use the blower
speeds shown on the furnace specifications to give a rise of 70 - 85°F. The #4 Lo
blower speed can be used for air circulation when neither heating nor cooling are
required. Set blower speeds to match the installation requirement.
3.10 COOLING – A/C MODELS
Air Conditioning models include a fan centre relay wired to run the blower at #1 Hi
speed when the cooling cycle is operating. For normal operation, select “AUTO” on the
T87F thermostat. When “FAN ON” is selected the blower runs constantly at the cooling
speed. See “OFF CYCLE AIR CIRCULATION”. For air conditioning, the blower on #1
speed will provide 1300 CFM at 0.50 in. wc static pressure.
Height of the coil above
the heat exchanger shall be no less than 4” (100 mm).
3.11 HUMIDIFIER
If a humidifier is installed ensure that no water can drip or run from it into the furnace.
This would cause deterioration and void the furnace warranty.
3.12 THERMOSTAT ANTICIPATOR SETTING
Thermostat anticipator setting should be 0.2 amps for any burner. Check that the
thermostat anticipator setting matches the primary control circuit current draw. This
setting affects the thermostat’s response to the control.
3.13 BLOCKED VENT SWITCH
ONLY APPLICABLE IN CANADA
NOT APPLICABLE FOR DIRECT VENT SYSTEMS
SWITCH
The blocked vent switches are flue gas spillage safety devices. They
OPERATION
detect spillage of flue gas products due to a blocked flue system or
inadequate draft. The switch senses the spillage of hot flue gases and
de-energizes the system’s burner control.
NEVER reset the blocked
vent switch, unless the cause of the blockage has been corrected.
INSTALLATION
1. Pierce a 5/8” hole into the flue vent pipe near the appliance breech connection.
2. This hole must be at least 10” before the draft regulator, top vertical or horizontal.
3. Remove one of the securing nuts from the threaded tube of the safety switch.
4. Tighten the other securing nut onto the pipe as far as possible.
5. Insert the threaded tube end into the pierced hole of the flue vent pipe.
6. Install the securing nut on the safety switch tube, which protrudes into the flue
vent pipe. “Tighten the nut securely.
