s long as the required clearance to combustibles is
maintained, the most desirable and benefi cial location
for an appliance is in the center of a building, thereby
allowing the most effi cient use of the heat created. The location of windows, doors and the traffi c fl ow in the
room where the appliance is to be located should be considered. If possible, you should choose a location
where the vent will pass through the house without cutting a fl oor or roof joist.
If the appliance is installed directly on carpeting, vinyl tile or other combustible material other than wood
fl ooring, the appliance shall be installed on a metal or wood panel extending the full width and depth.
Some appliances have optional fans or blowers. If an optional fan or blower is installed, the junction box must
be electrically connected and grounded in accordance with local codes, use the current CSA C22.1 Canadian
Electrical Code in Canada or the ANSI/NFPA 70 National Electrical code in the United States.
