These instructions should be used as a guideline and do not supersede local codes in any way. Install venting with
the most restrictive requirements as outlined in these instructions, local codes, these instructions, the current
National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CGA-B149.1 in Canada.
Ensure clearances are in accordance with local installation codes and the requirements of the gas supplier.
Vertical vent systems terminate through the roof. The minimum vent height above the roof and/or adjacent walls
is specified in ANSI Z223.1 (In Canada, the current CAN/CGA-B149.1 installation code) by major building codes.
Always consult your local codes for specific requirements. A general guide to follow is the gas vent rule (Table 6).
The following figures and their associated vertical vent tables illustrate the various configurations that are possible
for use with these fireplaces. Secure Vent
A table summarizes each configuration's minimum and maximum vertical and horizontal length parameters for a
variety of applications.
1. Refer to Figures 17 and 22, Tables 19, and 20 on Pages 27-28 to select the type of vertical installation desired.
