Failure to supply adequate combustion air for all appliance demands, may lead to back-drafting of those and other appliances. Outside air flex pipe goes here. When the appliance is side-wall vented: The air intake is best located on the same exterior wall as the exhaust vent outlet and located lower on the wall than the exhaust vent outlet. When the appliance is roof vented: The air intake is best located on the exterior wall oriented towards the prevailing wind direction during the heating season. The outside air connection will supply the demands of the pellet appliance, but consideration must be given to the total house demand.

If the chimney condition is questionable* you may want to install a liner as in method #7. In some places in the US and Canada it is required that the vent pipe extend all the way to the top of the chimney. *The chimney should be inspected and cleaned before installing your stove. If you discover that the chimney does not have a clay tile liner or has cracks or flaking of the tile liner you will need to install a stainless steel liner within the chimney. In most cases the inside diameter of this liner should be 4". Either flexible or rigid liner may be used for this purpose. Refer to Method 6 & 7.

The pipe or liner inside the chimney should be 4" diameter. In this method a cap should also be installed on the chimney to keep out rain. Be sure to use approved pellet vent pipe fittings. Seal pipe joints with silicone or aluminum tape in addition to the sealing system used by the manufacturer. Pipe size should be increased to 4" using this method.

    oPeration The PP38+ features two operating modes; stove temperature room temperature Mode Mode and room temperature Mode. In Stove Temperature Mode, you select a burn rate and the stove will remain at the same burn rate regardless of the room temperature. In the Room Temperature Mode, with the optional room sensor attached, the stove constantly monitors the temperature in the room and adjusts the size of the fire and the heat output of the stove so that the room is kept at a constant temperature. room temperature Mode Most consumers use the stove in the Room Temperature Mode because it is the easiest and most efficient method of keeping the room at a given temperature. In the Room Temperature Mode, the Room Sensing Probe constantly monitors room temperature. As the weather changes outside and your home needs varying amounts of heat to be at a desired temperature, the stove will automatically increase...
  • Page 16 oPeration stove temperature Mode stove temperature Mode In the Stove Temperature Mode, the stove can be adjusted to the desired setting using the same temperature control dial as is used in the Room Temperature Mode. The heat output and fuel consumption will remain constant regardless of room temperature. The settings from 1 to 7 on the inner ring of the temperature dial provide for relative heat output settings with 1 being low and 7 being the maximum. Never pull the plug to shut down the stove. This will stop the combustion blower and smoke will escape through window and door gaskets. Feed adjuster Knob For most premium grade pellet fuels the Feed Adjuster Knob should be set at 4. If higher ash fuels are used the setting should be increased to 5 or 6. Also higher settings are The setting above will produce continuous medium heat required if you would like to get the maximum heat output from output with the distribution blower at low speed.
