Maintenance
1. The appliance should be inspected before initial use
and inspected and cleaned at least annually by a
qualified field service person.
2. Tampering is DANGEROUS and voids all
warranties. Any component that is found to be faulty,
must be replaced with an approved component.
3. To obtain proper operation, it is imperative that the
burner flame characteristics are steady, not lifting or
floating. Check the burner flame patterns with Figure
13.
4. Periodically remove the logs and examine the
burner. If dirty, clean with a soft brush. Also examine
the area around the burner air shutter. Any dirt or lint
in this area should be removed. This will ensure long
life and trouble free operation. When the appliance
is put back in service, check the burner flame
patterns with Figure 17. Reinstall the logs as shown
in the log placement instructions.
5. Periodically check the hose connecting the LP gas
cylinder to ensure it is not damaged in any way.

High Elevation Installation

This U.L. listed gas appliance is tested and approved
for elevations form 0 to 2,000 feet in the US and from 0
to 4,500 feet in Canada.
When installing this appliance at an elevation above
2,000 feet (in the US), it may be necessary to decrease
the input rating by changing the existing burner orifice
to a smaller size. Input should be reduced four percent
(4%) for each 1,000 feet above sea level, unless the
heating value of the gas has been reduced, in which
case this general rule will not apply. To identify the
proper orifice size, check with the local gas utility.
When installing this fireplace at an elevation between
2,000 and 4,500 feet (in Canada), the input rating must
be reduced by ten percent (10%).
When installing this fireplace at an elevation above
4,500 feet (in Canada), check with local authorities.
Consult your local gas utility for assistance in
determining the proper orifice for your location.
