Installation Requirements

The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition. (EXCEP- TION: Do not derate this appliance for altitude. Main- tain the manifold pressure at 3.5” w.c. for Natural Gas, and 10” w.c. for Propane).

In Canada, installation must be in accordance with the current CSA B-149.1 Installation Codes and/or local

codes.

The installation should be done by a qualiﬁed service person, preferably NFI or WETT (Canada) certiﬁed who is familiar with the building codes and

installation techniques appropriate for your area to accomplish a safe and effective installation.

Your dealer or your local gas supplier will be able to refer a qualiﬁed service person.

away from furniture and draperies.

The surface of the Heater Is hot when it is in use. Young children should be watched carefully when they are in the same room when the Heater is in use, and they should be taught to avoid the hot surface. Keep any objects that can burn well away from the Heater, and observe the recommended clearances that follow.

Locating The Stove

In choosing a location for the stove, consider:

•The location of outside walls;

•Where additional heat is needed:

•Where family members gather most often;

•The vent system requirements.

NOTE: We do not recommend the use of wallpaper next to this stove. Over time, radiant heat may cause the wallpaper to shrink, or may adversely affect the binders in the wallpaper adhesive.

Clearance Requirements

Minimum Clearances to Combustible Materials

Measure side clearances as shown in Figures 3 and 4 from the outer edge of the cast iron stove top. Measure rear clearances from the outermost surface of the steel rear skirt.

The Jefferson heater is approved for installation into an alcove constructed of combustible materials to the dimensions and clearances shown on the next page.

The same clearances apply in a standard parallel instal- lation.

WARNING:

• Always maintain required clearances (air spaces) to nearby combustibles

to prevent ﬁre hazard. Do not ﬁll air spaces with insulation. All venting components must maintain a 1” (25 mm) clearance to com- bustible materials. Maintain a 6” (150 mm) clear- ance when using single wall pipe.

•The gas appliance and vent system must be vented directly to the outside of the building and never be attached to a chimney serving a separate solid fuel or gas-burning appliance.

•Refer to the manufacturer’s instructions includ- ed with the venting system for complete instal- lation procedures.
