The appliance must be isolated from the gas supply line by closing its individual manual gas shutoff valve (gas cock) during any pressure testing of the gas supply piping system that is equal to or exceeds pressures of 1/2 psig (3.5 kPa).
Inlet Pressure
MIN | MAX |
Natural Gas: 5.0 WC (1.24 kPa) | 7.0 WC (1.74 kPa) |
Propane: 12.0 WC (2.98 kPa) | 13.0 WC (3.23 kPa) |
| Manifold Pressure | |
| MIN | MAX |
Natural Gas: | 1.2 WC (0.29 kPa) | 3.8 WC (.95 kPa) |
Propane: | 2.9 WC (0.72 kPa) | 11.0 WC (2.74 kPa) |
ALWAYS TEST PRESSURE WITH VALVE CONTROL KNOB SET ON HIGH. Symptoms of incorrect gas pressure include:
Insufficient gas pressure:
•Small pilot flame which can result in insufficient millivolts.
•Little variation in flame picture between HI and LO settings.
•Insufficient gas to support more than one appli- ance causing nuisance outages or gas surges.
Excessive gas pressure:
•Permanent damage to valve causing complete appliance shut down.
•Too large a pilot flame resulting in overheating of the power generator and consequent shut down.
•Sooting due to impingement and/or incorrect fuel to air mix.
High Altitude Adjustment
Installations located at altitudes from 2000 - 4250 ft. (610 M - 1370 M), DONOT require adjustment. Do not derate this appliance for altitude.
