When the appliance is installed at elevations above 4,500ft (1372m), 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 (305mm). Expansion / contraction noises during heating up and cooling down cycles are normal and to
be expected.
Provided that the clearance to combustibles are achieved, the most desirable and benefi cial location for an
appliance is in the centre of a building, thereby allowing the most effi cient use of the heat created. The location
of windows, doors and the traffi c fl ow in the room where the appliance is to be located should be considered. If
possible, you should choose a location where the vent will pass through the house without cutting a fl oor or roof
joist.
This appliance is approved for closet or recessed installations, as well as for bathroom, bedroom and bed-sitting
room installations and is suitable for mobile home installations. The natural gas model can be installed in a mobile
home that is permanently positioned on its site and fueled with natural gas.
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.
Vented decorative gas appliance: not a source of heat; not for use with solid fuel.
