CERTIFIED
For Your Safety
Due to high temperatures, the appliance should be located out of
traffic and away from furniture and draperies.
Children and adults should be alerted to the hazard of high surface
temperature and should be kept away to avoid burns or clothing
ignition.
Installation and repair should be done by a qualified service person.
This series is design certified in accordance with American National
Standards Institute Z21.86 (latest standard) and CSA2.32-(latest
standard) by the Canadian Standards Association, as a Vented Wall
Furnace.
The installation must conform to local codes. In the absence of local
codes, the installation must conform with American National Standard
(National Fuel Gas Code) known as NFPA 54 and ANSI Z223.1 (latest
edition) available from the American National Standards Institute, Inc.,
11 West 42nd St., New York, N.Y. 10036, or from the National Fire
Protection Assoc., Batterymarch Park, Quincy, Massachusetts 02269.
Note: A vent safety switch is standard on all models, automatically
shutting off the heater in the event of a blocked flue or incorrect
installation. (Example: Attaching a 90° elbow directly to the draft
diverter is an incorrect installation.) The flue pipe diameter must be as
large as the flue collar on the draft diverter and run as directly as
possible to the chimney with a minimum of elbows. Any flue pipe
passing through walls and roof must be “B” Type vent. The chimney
must extend at least two feet above the roof and any object or
building within ten feet of the chimney.
Read your Owner's Manual for complete installation and safety information.
