This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for
use with other gases, unless a certifi ed kit is used.
When the appliance is installed at elevations above 4,500ft (1371m), and in the absence of specifi c
recommendations from the local authority having jurisdiction, the certifi ed high altitude input rating shall be
reduced at the rate of 4% for each additional 1,000ft (305m).
The switch on the battery holder must be placed in the middle position. If this switch is not in this
position the appliance will not operate using the remote, see “REMOTE RECEIVER INSTALLATION” and

Expansion / contraction noises during heating up and cooling down cycles are normal and are to be expected.
Change in fl ame appearance from “HI” to “LO” is more evident in natural gas than in propane.

The transmitter takes 3 “AAA” batteries and in the case of a power failure the battery back-up takes four “AA”
batteries.
