1. High Altitude Installation
For U.S. installation, appliances are tested and approved for elevations from 0-2000 feet. When installing this Imperial
Gas Log Set at an elevation above 2000 feet, National Fuel Gas Codes require a decrease of the input rating by changing
the existing burner orifi ce to a smaller size. Input should be reduced 4% for each 1000 feet above sea level. Check with
the local gas utility for proper orifice size identifi cation. The current orifice is available from your Heatilator distributor.
For Canada, appliances are certifi ed for elevations from 0-4500 feet. When installing this Imperial Gas Log Set at an
elevation between 0-4500 feet in Canada, the input rating does not need to be reduced. When installing this log set at an
elevation above 4500 feet in Canada, check with local authorities.

With proper installation and maintenance, your new decorative gas appliance should provide years of trouble-free service.
If you do experience a problem, refer to the troubleshooting guide below. This guide will assist you or a qualified service
technician in the diagnosis of problems and the corrective action to be taken.
N. Troubleshooting - “M” Series
Symptoms Possible Causes Corrective Action
1 Pilot sparks, but will not light
after repeated attempts. a. Main gas shutoff valve closed. Make sure that the shutoff valve located on the incoming gas line is open.
b. Air in the gas line. Bleed air out of the gas line. Retest for gas leaks
after bleeding.
c. Pilot orifi ce is plugged, not
allowing gas to fl ow.
This repair requires tools and some degree of
experience. Call a qualified service technician.
d. Misaligned electrode. Check spark gap; spark should be extending
approximately 1/8” to the pilot hood. Adjust gap to
give proper spark. Remove hands from electrode
before attempting to spark.
e. No gas supply to the appliance. Check plumbing to ensure the appliance has been
hooked up to the gas supply line.
The propane tank is empty.
f. Ground wire loose. Check that the black ground wire from the ignition
control box is securely attached to the ground.
g. Weak batteries. Replace with two new “D” sized batteries.
2 Pilot lights, but will not stay lit. a. Weak pilot flame. Pilot flame must engulf the fl ame sensor. Clean and/
or adjust pilot for maximum flame impingement on
flame sensor.
b. Loose wire connection Check for loose wires from the pilot to the ignition
control box.
c. Faulty fl ame sensor. Check the wire connection into the ignition control
box. If the connection is correct, replace sensor.
3 Pilot does not spark at all. a. Loose wire connection. Check for loose wires from On/Off switch to ignition
control and remote control.
b. Remote control. Make sure the switch located on the front of the
remote control is set to the “Remote” setting.
c. Weak batteries. Replace with two new “D” sized batteries.
