Initial Installation QUALIFIED INSTALLERS ONLY PLANNING YOUR INSTALLATION: When planning your installation, it will be necessary to select the proper length of vent pipe for your particular requirements. It is important to note when passing through a wall, the maximum allowable wall thickness is 10 inches (25.4 cm), 11⁄2 inches (3.8 cm) clearance to combustibles must be maintained. Select the amount of vertical rise desired for “vertical-to-horizontal” type installations.
Initial Installation QUALIFIED INSTALLERS ONLY HORIZONTAL INSTALLATION: STEP 1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the way when the venting system is attached. If this is the case, you may want to adjust the location of the appliance. STEP 2. Direct vent pipe and fittings are designed with special twist-lock connections.
Initial Installation QUALIFIED INSTALLERS ONLY STEP 3. With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4 cm) x 10” (25.4 cm) square hole (refer to Figure 13). The center of the square hole should match the center line of the horizontal pipe. Cut and frame the 10” (25.4 cm) x 10” (25.4 cm) hole in the exterior wall where the vent will be terminated. Refer to Figure 8. If the wall being penetrated is constructed of non-combustible material i.e.
Initial Installation Interior Wall Surface 2.5" (64mm) Inside Finished Collar NOTES: (1) The horizontal run of vent pipe must be level and should have a 1⁄4 inch rise for every one foot of run towards the termination. Never allow the vent to run downward. This could cause high temperature and may present the possibility of a fire.
Initial Installation QUALIFIED INSTALLERS ONLY VERTICAL INSTALLATION: STEP 1. Check the instructions for required clearances (air spaces) to combustibles when passing through ceilings, walls, roofs, enclosures, attic rafters, or other nearby combustible surfaces. Do not pack air spaces with insulation. STEP 2. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to the position of the appliance flue exit, and mark the location where the vent will penetrate the ceiling.
Initial Installation QUALIFIED INSTALLERS ONLY STEP 6. Once the pipe sections have been joined, and run up through the hole in the roof, slip an elbow strap over the exposed sections, bend the support straps outwards, and push the elbow strap down to the roof level, as shown in Figure 21. Tighten the clamp around the pipe section. Use a level to make sure the pipe is truly vertical. With roofing nails, secure the support straps to the roof. Seal the nails holes heads with non-hardening mastic.
Initial Installation QUALIFIED INSTALLERS ONLY FREESTANDING DRAFTHOOD ADAPTOR: This Drafthood Adaptor is a complete assembly and is ready to fit onto your Westport in a vertical vent application only. With the Drafthood Adaptor correctly installed and wired to the gas control valve. Your Direct Vent Fireplace can be vented like a B-Vent Fireplace. INSTALLATION: WARNING: This Freestanding Drafthood Adaptor must be fitted by a qualified service technician.
Initial Installation GENERAL VENTING INFORMATION: Canadian Installations The venting system must be installed in accordance with the current CSA B149 installation code and/or local codes having jurisdiction. U.S.A. Installations The venting system must be installed in accordance with the current National Fuel Gas Code, ANSI Z223.1, and/or local codes having jurisdiction. The minimum clearance to combustibles is 6” (150 mm) when using single wall venting and 1” (25 mm) when using “B-vent” venting.
Initial Installation 4. After a minimum of 10 minutes operation, test the chimney draft with a smoke match at the top row of the pattern to confirm that there is adequate draft or ‘pull’ at the openings around the body of the Drafthood Adaptor, as shown in Figure 26. AUTOMATIC SAFETY SHUT DOWN: If the spill switch is activated and shuts off the main burner the following procedure should be followed. • Is the pilot flame still on? If not, the reason for the fireplace shut down is not the spill switch.
Initial Installation HEARTH MOUNT INSTALLATION: This unit may be installed as a hearth mounted unit. Install two 3’ inch pipes up the chimney to a seal plate and cap assembly, one exhaust pipe, and one air intake pipe Using venting manufactures coaxial to co-linear adapters at the unit and at the chimney termination. Maximum vertical chimney height 15 feet (4.57 m) Seal Plate & Cap Assembly 2"-3" (51mm-76mm) Collinear Pipes 15 feet (4.
Initial Installation GAS LINE CONNECTION AND TESTING: WARNING: Only persons licensed to work with gas piping may make the necessary gas connections to this appliance. GAS LINE CONNECTION • This stove is equipped with a certified flexible pipe located on the right side of the unit terminating in a 3⁄8” male NPT fitting.
Initial Installation ELECTRICAL REQUIREMENTS: The ENVIRO ASCOT will operate without electrical power. This model has a millivolt gas control, which uses the pilot flame to generate enough electricity to operate the main burners. The appliance when equipped with an optional blower must be electrically connected and grounded in accordance with local codes or in the absence of local codes, with the current CSA C22.
Secondary Installation INSTALLATION OF LOG SET AND EMBERS: The placement of the logs is not arbitrary. If they are positioned incorrectly, the flames can be “pinched” and will not burn correctly. The burner come with four (4) locator pins (see Figure 32), and the bottom logs have ledges which make alignment easier. Using the pictures provided, carefully set the logs in place. NOTE: The logs are fragile and should be handled gently. Placement pegs for bottom left log. Placement pegs for bottom right log.
Secondary Installation 3. A bag of ceramic fiber embers and rock wool embers is provided gently remove the ember material from the plastic bag. Spread a layer loosely across the burner tray. Do not allow any embers to rest against pilot assembly. (See diagram provided for proper ember placement.) 4. DO NOT pack this ember material as this could create an unsafe condition, leave embers loose Figure 36. Log Placement Step 4. 5. Upon the first light up, watch for ignition to ALL burner ports.
Trouble Shooting Problem Possible Cause Spark will not light the Defective piezo ignitor. pilot after repeatedly pressing the spark ignitor Solution • Check connections to ignitor. • If ignitor connections are good but no spark, replace ignitor. Broken spark electrode. • Check for broken ceramic insulation, replace electrode if broken. Low battery or bad electronic module. • Replace the electronic module or replace the battery in module. Misaligned spark electrode.
