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 ¼” 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: No combustion air supply may 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 ECO-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, 7th 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 with 500°F (260°C) RTV silicone sealant to ensure consistent performance and avoid smoke spillage. All horizontal connector joints must be sealed with UL-181-AP foil tape. We recommend that all vertical vent connector joints be secured with a minimum of 3 screws.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.

INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.

WARNING: DO NOT INSTALL IN SLEEPING ROOM

CAUTION: THE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL, AND CEILING/ROOF MUST BE MAINTAINED
