2" ADJACENT WALL 2" 3" 3" 6" 6" 6" FIGURE 2 Corner installation FIGURE 3 Floor protection 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 .” 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 floor near stove rear terminating only in a ventilated crawl space. • A hole in the wall behind the stove. 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 closeable outside air register can be used in tightly insulated homes. VENTING The ECO-45 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 25 3 16 3211 16 EXHAUST AIR INTAKE 4 5 4 16 7 16 91 2 117 8 TRIM COLLAR RODENT GUARD VENTILATED CRAWL SPACE 6 INSTALLATION FIGURE 4 Rear view FIGURE 5 Fresh air supply FIGURE 6 Fresh air supply INSSTTAALLLLAATTIIOONN 7 Equivalent Vent Length (EVL) The longer the run of pipe in your installation, the more restriction there is in the system. Therefore, larger diameter pipe should be used. • Use 4” pipe if you have more than 15 feet of Equivalent Vent Length (EVL). • Horizontal runs shall not exceed 10 feet of EVL. • To calculate EVL, use the following conversions table: Qty Type of pipe EVL equivalent(ft) 1 90° elbow or “T” 5 1 45° elbow 3 1 ft Horizontal pipe run 1 1 ft Vertical pipe run 0.5 NOTE: At altitudes above 3,000 feet, we suggest the use of 4” diameter vent at an EVL of 7 feet or more. Here is an example on how to calculate the EVL of your installation. (See Figure 8) (3 x 4’ of vertical length = 12’ x 0.5 = 6 EVL) + (1 x elbow or "T" = 5 EVL) + (2 x 1’ of horizontal length = 2 EVL) Total EVL = (6 + 5 +2) = 13. So 3” diameter vent is allowed INSTALLATION CONFIGURATIONS A. HORIZONTALLY THROUGH WALL (refer to Figure 7 & 8) NOTE: Follow the vent manufacturer’s instructions. 1. Position stove, adhering to clearances shown in Figures 1 & 2. 2. Locate position of hole in wall; directly behind stove exhaust vent (refer to figure 4). 3. Always maintain 3” clearance from combustible materials. 4. Install a wall thimble as per the vent manufacturer’s instructions. 5. Attach enough piping to penetrate and extend at least 6” beyond exterior walls. An 8-foot vertical pipe run is suggested where possible to reduce the possibility of smoke spillage in the event of a loss of negative pressure. 6. Attach cap and seal outside wall thimbles with non-hardening waterproof mastic. Termination should not be located so that hot exhaust gases can ignite trees, shrubs, or grasses or be a hazard to children. Exhaust gases can reach temperatures of 500.F and cause serious burns if touched.
