INTERIOR INSTALLATION 4 Remove the template from the wall after the wall openings are marked. The wall opening location markings should be present on the wall. Ensure the wall studs do not interfere with the wall opening. 5 Pilot Hole Drill a pilot hole inside of the traced circle so that a saw can be used to cut the wall openings out. 6 Use a saw to cut the wall openings out of the wall and discard the inner circle debris.
INTERIOR INSTALLATION 7 Before installing unit, remove wall mounting plate from back of unit. 8 Push on bottom of casing door to open it. Pivot and remove casing door. Remove two screws from the back inside of the unit and detach the wall mounting plate from outside back of the unit. 9 Locate the studs in the wall and use at least four wood screws to attach the wall mounting plate to the wall. If installing onto drywall (not into a stud), anchors must be used.
INTERIOR INSTALLATION 11 The optional thermostat bracket can be installed directly to the left or right side of the wall mounting plate. Use two #8 x 3/8in screws (provided) to attach the thermostat bracket to the wall mounting plate as shown. 12 Thread one end of the thermostat wire through bracket and the wall mounting plate as shown. 13 Split the thermostat wire at the top and thread the ends through the rear of the optional thermostat to the front.
INTERIOR INSTALLATION 15 Line up the two tabs on the top of the wall mounting plate with the slots in the back of the unit. Slide the back of the unit onto the tabs of the wall mounting plate. 16 Secure the back of the unit into place using two screws removed in step 8.
INTERIOR INSTALLATION 17 GAS LINE After the back of the unit is attached to the wall, bring in the gas line as shown on page 15, or follow the installation template indications. Following your city, local and state codes, attach the gas line to the unit. CAUTION: Grasp wrench on regulator when installing gas inlet. NOTE: The gas line can come through the wall or floor of the house. 18 Thread the thermostat wire through the oblong hole in the rear of the heater casing.
CUTTING THE VENT TUBES NOTE: Flue outlet tube and air inlet tube should be measured and cut to the proper length from the back of the unit to the outside wall of the house.
