The wall gets hot behind my gas heater
The wall on the back side of the wall heater gets very hot, what can I do about this On 2019-02-05 by Dan
by (mod) - Safety warning
Dan:
Watch out: First recognize that there could be a fire hazard - the building could catch on fire - or the heater may not be installed properly or not working properly.
That means turn the heater off until you know that it is safe.
Next: Identify the heater brand and model - check the heater's data tag.
Then give the manufacturer a call to find out if in their opinion there is a safety hazard.
While you're at it get the installation and operation manual for your specific heater to make it easy to check the installation specifications against your particular case.
If you cannot identify the heater brand and model and contact the manufacturer leave the heater off while you arrange a fire/safety inspection by a trained heating service technician for your heater type, presumably gas-fired but possibly electric or oil or other.

Most wall furnaces use an air filter that needs to be cleaned or replaced. For example here's a typical quote from an Empire wall heater manual
IMPORTANT: This furnace has a washable permanent type filter in the door which should be cleaned at least once per year before the heating season.For dirty or high use areas more frequent cleaning is required.
HOWEVER the specific manual for your heater does not mention an air filter.
P. 25 contains these instructionsKeep burner and control compartment clean.
Installation and repair should be done by a qualified service person.
The appliance should be inspected before use and at least annually by a qualified service person.
More frequent cleaning may be required due to excessive lint from carpeting, bedding materials, etc. It is imperative that control compartments, burners and circulating air passageways of the appliance be kept clean.
