“High”, “Off”, and the “Low” settings.
Safety controls:
A safety switch will shut the system down in the event of any one of the following conditions:
Incorrectly installed vent system
Blocked vent causing flue spillage
Flow reversal or sustained down draft situation
Drafthood:
The appliance is provided with a drafthood design, which minimizes the effects of down drafts or
flue blockages on the quality of combustion. It will vent out of the appliance upon down draft or
flue blockage and, by design, it exhausts to the same pressure zone as the combustion air inlet
to the appliance.
1.3 INTENDED USE
This appliance is intended to be used as a heater, when installed as an insert for code complying
masonry, or listed factory built solid fuel burning fireplaces which meet the minimum requirements as
described in detail in the installation instructions. This insert is certified for installation in a bedroom
or a bed sitting room where the maximum input is within 50 cubic feet per 1000 Btu/hr, (i.e. 1250
cubic feet). All bedroom installations require the use of wall thermostats.
