How to Install a Gas Wall Heater - Page 2

Step 2 : Attach the mounting bracket

Attach the unit's mounting bracket to the wall. Gas space heaters are typically not heavy, but for safety's sake it is better to mount the bracket directly to one or more wall studs, rather than to drywall only. Use screws long enough to penetrate through the bracket and wall surface and at least half their length into the studs.

Step 3 : Lay out the supply pipe

Lay out your gas supply pipe run, beginning at the gas meter where it enters your house. Different municipalities have different pipe size and material standards. Copper or flexible stainless steel tubing, which is sold in continuous rolls, is easiest to install. If either one may be used in your locality, try to map a pipe run that can be accomplished without cutting or jointing the tubing between the meter and the appliance.

If jointing is required, the tubing must be flared, and compression fittings should be installed by your professional installer. If you have to use "black iron" pipe, the job is more difficult because the rigid pipe must be cut to specific lengths and threaded for fittings. This requires special tools and skills, and usually more time on the job. However, pre-cut, pre-threaded lengths are available, which you can temporarily fit and mount in preparation for your pro's visit. You can also bore holes through walls and framing to run the pipe, which will speed the final installation.

Step 4 : Make the wiring connections

Mount the heater to the wall bracket and make any wiring connections according to National Electrical Code regulations.

Heaters with metal cabinets usually have a built-in panel for these connections, and do not require a separate junction box or switch.
