COMBUSTION AIR SUPPLY
For a mobile home installation the stove must be connected to an outside
source of combustion air. A 3” inside diameter metallic pipe, either flexible
or rigid, may be attached to the inlet at the stove’s rear (refer to figures 4, 5
& 6). A rodent guard (minimum 1/4” wire mesh) must be used at the
terminus (refer to figure 5). All connections must be secured and airtight by
either using the appropriately sized hose clamp and/or UL-181-AP foil tape.
For mobile home installations only: combustion air supply conduit may
not exceed 10 feet.
Sources of Outside Combustion Air
•
A hole in the wall behind the stove.(Figure 5)
•
A hole in floor near stove rear terminating only in a ventilated
crawl space.(Figure 6)
WHEN OUTSIDE AIR IS NOT USED
If outside air is not used, it is important that combustion air be easily
available to the air inlet. A closable outside air register can be used in
tightly insulated homes.
VENTING
The HYBRID-35 is certified for use with a vent certified to UL-103 or ULC
S629M and a chimney type vent certified to UL-641 or ULC-S-609-M89
and ULC/ORD C441-M90, with 3” or 4” inner diameter. In Canada, we
recommend that you use
a listed pellet vent that meets the ULC S-609-M89
and ULC/ORD C441-M90 Standards. For the United States, we
recommend that you use a listed pellet vent that meets the UL-641, 7
th
edition Standard. This unit can be vented in an existing chimney with the
addition of a liner if the chimney is more than 4” in diameter. Class “A”
chimney is not required. Refer to the instructions provided by the vent or
chimney manufacturer, especially when passing through a wall, ceiling, or
roof.
Your venting system should have at least one foot of vertical rise for
each foot of horizontal run. The total vertical rise should never be
less than 3 feet (see Appendix A).
This is a pressurized exhaust system. All vent connector joints must be
sealed and fastened in accordance with the pellet pipe manufacturer's
instructions to ensure consistent performance and avoid smoke and ash
spillage.
