Introduction – 5 Introduction Please read our instructions before you install and use your furnace. This will help you obtain the full value from this furnace. It will also help you avoid any needless service costs if the problem is found within this instruction manual. Always consult your local heating or plumbing inspector, building department or electric utility company regarding regulations, codes or ordinances which apply to the installation of a Direct-Vent Wall Furnace.
PAGE 6
Installation Locating Wall Furnace Consider the following points before attempting to install the furnace. All Models 1. This is a direct-vent wall furnace. It must be installed on an outside wall for proper venting of flue gases. (Figure 1). 2. Wall furnace must be surface mounted on an outside wall up to 24-inches thick when using an optional Vent Extension Kit. 3. Check the clearances needed from the furnace and vent. (Figure 1 and 2).
PAGE 7
Installation Drill a 1/4 inch hole in the wall at the vent opening center mark all the way through to the outside. Cut the 9-1/4 inch diameter hole through the inside wall. Using the 1/4 inch hole as center, cut a matching hole in the outside wall. It may be better to work from the outside when breaking through brick, stone or tile.
PAGE 8
Installation FIGURE 4 If the wall surface is not flat (shiplapped siding, etc.) or less than 5 inches thick, use a Thin Wall Collar Kit (9307) or, build up a flat surface with wood strips. Do not tilt or bend the cap to fit uneven surfaces. The vent cap flange must be tight against the wall to prevent rain or wind penetration. Use standard caulking compound if required (not provided).
PAGE 9
Installation Thermostat Installation Wall Mounting 1. If an existing thermostat is being replaced and is in a satisfactory location and the wiring is in good condition, use existing wiring. If in doubt, use new wiring. 2. If a new location is chosen or if this is a new installation, the thermostat wire must first be run to the location selected. All wiring must agree with local codes and ordinances.
PAGE 10
Installation Thermostat Mounting FIGURE 9 1. To remove the thermostat cover, grasp cover and squeeze both sides firmly, then lift to remove cover. Carefully remove and discard the packing tab protecting the switch contacts. 2. Connect thermostat wires to the terminal screws on the front of thermostat base. 3. Push any excess wire back through hole in the wall and plug the hole with insulation to prevent drafts from affecting thermostat operation. 4. Being sure to level thermostat for the best appearance.
PAGE 11
Installation Cabinet Installation 14038 Series: Set the cabinet over the furnace body, dropping the rear top flange between the support legs and wall. Open the cabinet door and attach the cabinet to the inner casing with two (2) sheet metal screws. (Figure 10). FIGURE 10 22038 Series: Set the cabinet over the furnace body, dropping the rear top flange into the slot in top of the spacer plate and into the slots between the support legs and wall.
PAGE 12
Installation Orifice Sizes The efficiency rating of these appliances is a product thermal efficiency rating determined under continuous operating conditions and determined independently of any installed system. For elevations above 2,000 feet reduce ratings 4% for each 1,000 feet above sea level. 3. Use ground joint unions. The correct orifice sizes for the different input ratings when using natural or L.P. gas are: 4.
PAGE 13
Installation FIGURE 13 FIGURE 14 Checking the Gas Piping Test all piping for leaks. When checking gas piping to the furnace with gas pressure at less than 1/2 PSI, shut off manual gas valve to the furnace. If the gas piping is to be checked with the pressure at or above 1/2 PSI, the furnace and manual shutoff valve must be disconnected during testing. Apply a soap solution (or a liquid detergent) to each joint. Bubbles forming indicate a leak. Correct even the slightest leak at once.
PAGE 14
Operating Your Furnace The furnace operates in the following sequence: 1. The thermostat turns on the main burner. Input and output ratings shown on the rating plate, located in burner compartment, must not be exceeded. IMPORTANT: KEEP BURNER COMPARTMENT CLEAN. 2. Heat builds up in the furnace and starts the fan (if equipped). The heated air comes out the panel louvers. AND CONTROL 3. When the thermostat setting is reached, it shuts off the main burner.
PAGE 15
Operating Your Furnace Operating Instructions 1. STOP! Read the safety information above. 2. 3. 4. 5. Set the thermostat to lowest setting. If applicable, tum off all electric power to the appliance. Open the control access panel. Push in the gas control knob slightly and turn it clockwise to “OFF”. NOTE: The knob cannot be turned from "PILOT' to "OFF" unless the knob is pushed in slightly. Do not use force. 6. Wait five (5) minutes to clear out any gas, then smell for gas, including near the floor.
PAGE 16
Operating Your Furnace Type of Gas Natural L.P. Manifold Pressure, In W.C. 4 10 pressure. Increase or decrease the pilot flame to obtain proper setting. FIGURE 15 The rated input will be obtained on 2,500 Btu of propane at 10 inches manifold pressure with factory-sized orifices. If L.P. Gas having a different value is supplied, orifices must be changed by a qualified installer before the furnace is operated.
PAGE 17
How to Care for Your Furnace Abnormal Appearance Lazy Flame: Long soft yellow cones moving around in the combustion chamber lifting from ports (insufficient air). Extremely Fast Flame: Will not hold to ports - entire cone sections blow off from noisy ports (too much pressure). Vent System Check the vent cap and tubes to be sure there are no blocked inlet air or flue openings. The flow of combustion and ventilation air must not be obstructed. Clean or replace before using the furnace.
PAGE 18
Installations in the State of Massachusetts All installations in the State of Massachusetts must use the following requirements when installing, maintaining or operating direct-vent propane or natural gas-fired space furnaces. For direct-vent appliances, mechanical-vent heating appliances or domestic hot water equipment, where the bottom of the vent terminal and the air intake is installed below four feet above grade the following requirements must be satisfied: 1.

Blower Accessory 2302 and 2303 This accessory can be operated using the factory equipped three-prong (grounding) plug and cord or may be field wired. See field wiring installation instructions below. When using the plug and cord, for your protection against shock hazard, it must be plugged directly into a properly grounded three- prong receptacle. DO NOT REMOVE THE PRONG. All electrical work must conform to your local codes and ordinances, or in their absence, with National Electrical Code ANSI/NFPA 70.
PAGE 20
Blower Accessory 2302 and 2303 Note: If any of the original wire as supplied with the appliance has to be replaced, use only 18 Ga., 4/64 insulation, 105 C AWM wire or its equivalent 115V, 60Hz, - less than 3 amps.
