11 11. INSTALLATION Required floor, ceiling, and roof cut-out open- ings must be carefully located to avoid misalign- ment of the furnace and Roof Jack (see Figures 12 & 13). Installation procedures are suggested for typical furnace installations and need not be followed in the exact listed sequence.

16 If the heat anticipator is set too low, the furnace may cycle frequently and not provide comfort to the homeowner. 14 . FUEL PIPING Sizing and installation of fuel lines must be in accordance with federal, state and local regu- lations. All piping shall be black iron pipe, or equivalently sized steel tubing.

19 ground. Fuel tanks may also be buried if prop- erly coated to resist corrosion. For below ground fuel tank installations, the vertical dimension from the bottom of the fuel tank to the fuel pump must not exceed ten feet. Keep the tank filled, especially in the summer to reduce the accu- mulation of condensation.
20 15 . FLUE GAS SAMPLING It may be necessary to take flue gas sampling from oil and gas gun furnaces (M1S and M1B Series Models) in order to check the perfor- mance after furnace installation. A flue gas sample may be taken from the heat exchanger, which is located behind the hole of the top-front of blower compartment.

If fire door is open or spring is broken it may allow products of combustion into the living space by the furnace blower resulting in possible asphyxiation.
22 e. When the call for heat is satisfied the thermo- stat contacts open, the gas valve shuts off gas flow, and the induced draft blower stops. GENERAL-DIRECT IGNITION MODELS Read safety information on front page of these installation instructions before operating fur- nace.
23 remains open if flame is sensed, or closes if flame is not sensed. e. If flame is not sensed, the entire sequence is repeated four more times before “lockout” occurs. To reset, wait 30 seconds and then interrupt the 24 VAC power by turning the room thermostat below room temperature, then returning it to the original set point.
24 accomplished automatically by a silicon car- bide hot surface ignitor. A control module takes care of all lighting and timing functions. There are no external relays or timing devices. Do not try to light this furnace manually. The control module is not field serviceable.
25 2. Limit Control - This furnace is protected by two high temperature safety limit switches. The auxiliary (upper) limit switch and the high temperature (lower) limit switch are auto- matic reset types. If either limit trips, the burner will shut off.
26 5/32” GAP ELECTRODE NOZZLE 0-1/16” 5/16” ABOVE CL Gently tighten the lock nuts after completing the adjustment. For best results, use instrument to measure between 8-9% CO 2 , after the com- bustion air has been adjusted. Note: Do not over-tighten the lock nuts, otherwise the plastic air shutter may be damaged.
27 d. To remove the gas valve assembly, remove screw(s) from gas valve bracket. Gas valve and spud may be removed. Orifice is located at the end of the spud (M1G*,M1M*),or re- move three (3) bolts from U-shaped manifold plate and orifice assembly (M1B*).
28 may be defective. Replace the gas valve if necessary. e. Be sure the pilot shield is in place. f. Check for gas leaks in the pilot line or the pilot assembly. g. Check the flue assembly to make sure all connections are tight. h. See the FURNACE START-UP procedure for lighting details.
29 humidity requires higher temperatures for the same level of comfort. Check for proper humidity level in the home. TROUBLESHOOTING - DIRECT IGNITION FURNACES INCLUDING GAS GUN Burner Motor Does Not Run— Thermostat Calls For Heat a. Check the electrical supply to the furnace.
30 c . If no power to combustion blower then check wiring and control module; replace if neces- sary. Circulation Air Blower Will Not Operate Even Though The Burner Does Operate a. Check thermostat “G” wiring. b. Check wiring to motor. c . Check for a defective motor.
31 ! W ARNING: Do not obstruct any return air open- ings, including the grille on the fur- nace. To do so may cause the furnace to activate the high limit and shut down, or it may cause asphyxiation.
