INSTALLATION
VENTING
1)This fireplace must be vented with a 4" (100mm) diameter Class “B” vent. The installation of the venting system must conform and be in accordance with the natural gas installation code CAN/CGA - B149 (Canada), ANSI Z223.1 (U.S.A.), AG 601 (Australia), and NZS 5261 (New Zealand). Minimum chimney height from base of fireplace must be at least 12 feet (3.7m).
2)Masonry Chimney Installation:
This application can be connected to a masonry chimney flue. Make sure the masonry chimney is clean and in good working order. When an existing masonry chimney is unlined and local experience indicates that gas condensation may be a problem or if local codes dictate, an approved liner should be installed. Use “B” Vent to bridge the gap between the fireplace and the masonry chimney. To ensure proper flue sizing and operation it is recommended that the masonry chimney be lined with an approved aluminium chimney liner of the same diameter as the “B” Vent. Make sure connection between “B” Vent and masonry is completely sealed. Flue pipe exposed to cold air should be insulated in a chase. If condensation occurs, a trap should be installed at bottom of flue.
Use a maximum of two offsets; four 45o elbows, or two 90o elbows for example. Slope horizontal pipe at least 1/4" (6.4 mm) rise per foot of run. Horizontal runs should not exceed the vertical rise. Keep horizontal runs to a minimum. See chart below.
NOTE: Cold Climate Installation
When this appliance is to be installed against a non- insulated wall or in a chase, fibreglass insulation should be installed around the body of the fireplace.
Note: The draft hood must be installed parallel to the
fireplace opening, as shown below. See
Instructions in U20/E21 Installation Manual.
