Initial Installation QUALIFIED INSTALLERS ONLY WARNING: Operation of this heater when not connected to a properly installed and maintained venting system can result in carbon monoxide (CO) poisoning and possible death. PREPARATION FOR INSTALLATION: • Remove the packaging from the appliance, and check to make sure there is no damage. If damage is found, please report it to both the carrier and your dealer as soon as possible.
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 22). 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 15. 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: Exterior Wall Surface (1) The horizontal run of vent pipe must be level and should have a 1⁄4” 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: 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. 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 elbow strap down to the roof level, as shown in Figure 30. 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. Trim the excess length of the support straps that extend out beyond the edge of the flashing. 7. Slip the flashing over the pipe section protruding through the roof.
Initial Installation QUALIFIED INSTALLERS ONLY NOTES: (a) If an offset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3 feet (91 cm), to avoid excessive stress on the elbows, and possible separation. Wall straps are available for this purpose (see Figure 32). (b) When ever possible, use 45° degree elbows instead of 90° degree elbows. The 45° degree elbow offers less restriction to the flow of flue gases and intake air. (c) For multi story installations.
Initial Installation QUALIFIED INSTALLERS ONLY FREESTANDING DRAFTHOOD ADAPTOR - 50-841: 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. 1.
Initial Installation The minimum clearance to combustibles is 6” (150 mm) when using single wall venting and 1” (25 mm) when using “B-vent” venting. We strongly recommend installing an approved chimney liner in an existing brick chimney. This will maximize the potential draft of the chimney and lessen the effects of slow chimney start-up. VENTING OF A FIREPLACE FITTED WITH THE DRAFTHOOD ADAPTOR: Note: Please refer to the chimney manufacturer’s installation instructions prior to commencing the installation.
Initial Installation 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. • Turn off the pilot flame and turn off all controls. Let fireplace to cool down. Refer to Owner’s Manual. • Check for blockages or restrictions in the flue and venting components. • Restart the fireplace and check for vent draft as described earlier.
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 48), and the bottom logs have ledges which make alignment easier. Using the pictures Placement pegs for provided, carefully set the bottom left log. Placement pegs for logs in place. bottom right log. NOTE: The logs are fragile and should be handled gently.
Secondary Installation Ledges for top right log. 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.) Figure 51. Log Placement Step 3. 4. DO NOT pack this ember material as this could create an unsafe condition, leave embers loose 5.
Secondary Installation Important note: When the unit is turned on for the first time, It should be turned onto high without the fan on for the first 4 hours. This will cure the paint, logs, gasket material and the other products used in the manufacturing process. It is advisable to open a window or door, as the unit will start to smoke and can irritate some people.
