3. Low gas pressure. 4. Pilot decreases in size when main burners come on. 5. Air shutter open too far. 6. Drafts around appliance. 7. Bad venting. 1. Check pilot orifice, increase pilot gas flow if necessary by adjusting inlet pressure. 2. Clean burner ports (Do not enlarge ports). 3. Check gas supply pressure. 4. Supply piping is inadequately sized. Consult local gas utility or competent installer. 5. Close air shutter to proper setting as outlined in these instructions (slight yellow tipping is allowable on L.P. Gas). (See Page 12). 6. Eliminate drafts. 7. See “Venting”. Failure to Ignite 1. Main gas off. 2. Defective gas valve. 1. Open all manual gas valves. 2. Replace gas valve. Condensation of water vapor1. Improper venting. 1. See “Venting”. Burner won’t turn off 1. Defective or sticking automatic valve. 2. Excessive gas pressure (The supply gas pressure must not exceed 1/2 psi or 14” water column). 1. Clean or replace valve. 2. To correct this situation contact the utilitysupplying the gas. Incorrect gas input 1. Gas input not checked. 1. Re-check gas input. 2. Clogged orifice. 2. Check orifice for clogging. If clogged, clean out the hole carefully with a smooth wood toothpick. (Do not in any way enlarge or distort it). Not enough heat 1. Appliance undersized. 2. Temperature dial set too low. (Bulb type valves). 3. Incorrect supply pressure. 1. This is especially true when a dwelling or room is enlarged. Have the heat loss calculated and compare to the appliance output (70% of input). Your gas company or installer can supply you with this information. If appliance is undersized, replace with correct size unit. 2. Raise setting of Temperature Dial. See “Lighting and Shutting Down Instructions”. 3. Check supply pressure as outlined above. Too much heat 1. Temperature dial set too high. 2. Combination control valve sticks open. 1. Lower setting of temperature dial. See “Lighting and Shutting Down Instructions”. 2. Replace combination control valve. Page 15 TROUBLE SHOOTING CHART - AUTOMATIC PILOT & VALVE SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION Burner won’t turn on1. Pilot flame too large or too small. 2. Dirt in pilot orifice. 3. Defective automatic pilot section in combination control valve. 4. Defective thermocouple. 5. Defective combination control valve. 6. Wall thermostat models - manual reset blocked flue switch tripped. 1. Re-adjust pilot flame using adjustment on combination control valve. 2. Clean pilot orifice with air or solvent, do not ream. 3. Replace entire combination control valve. 4. Replace thermocouple. 5. Replace valve. 6. Reset switch, see Page 6 and blocked fluesection below. TROUBLE SHOOTING CHART - BLOCKED FLUE SWITCH (FOR USE BY A QUALIFIED SERVICEMAN) POSSIBLE CAUSES CORRECTIVE ACTION 1. Blockage in vent pipe A. Check vent pipe for blockage, such as bird nest, wasp nest, twigs, leaves, etc. B. Check inside the bottom of the vent pipe to make sure the top of the draft diverter did not rip the inner liner causing it to block part of the vent opening. C. Check that no insulation from the header plate got caught on top of the draft diverter when the heater was inserted into the wall. D. Check that the vent cap is properly installed, not shoved too far down on the vent pipe. 2. Burner is overfiring A. Check the manifold pressure. B. Check the rate, NOTE: This appliance was orificed for elevations up to 2,000 feet. When installed at higher elevations refer to orifice chart in controls section of instructions for proper orifice size and re-orifice accordingly. 3. Improper vent system A. Vent too short B. Restriction in vent systemcaused by offsetsC. Incorrect vent pipe 3. Correct vent system. A. The vent should terminate a minimum of 12 feet above the floor. See Figure 2. Also, the top of the vent must be at least 2 foot above any obstacle within a 10 foot radius, including the roof. See Figure A. B. All type “B” vents shall extend in a generally vertical direction with offsets not exceeding 45 degrees, except that a vent system having not more than one 60 degree offset may be allowed. Any angle greater than 45 degrees from the vertical is considered horizontal. The total horizontal run of a vent plus the horizontal vent connector shall be not greater than 75 percent of the vertical height of the vent. Any offsets used should be as far above the drafthood as possible to allow a venting action to begin before any restriction is encountered. C. Use listed BW type vent pipe. Do not use tansite or any other type of ceramic pipe for venting. Do not use single wall pipe. When venting into a masonry chimney the chimney must be properly lined and sized for this gas furnace. The use of type B or flexible chimney liner is recommended. 4. Incorrect header plate location4. The header plate must be 65-3/4” above the floor plate. See rough-in instructions. 5. Vent pipe not down on the header plate securely 5. Use a base plate (obtained from the vent pipe manufacturer) on top of our header plate....
