COMBAT® UHA UNIT HEATER INSTALLATION OPERATION AND SERVICE MANUAL

SECTION 2: INSTALLER RESPONSIBILITY

The installer is responsible for the following:

•To install the heater, as well as the gas and electrical supplies, in accordance with applicable specifications and codes. Roberts-Gordon recommends the installer contact a Local Building Inspector or Fire Marshal for guidance.

•To use the information given in a layout drawing and in the manual together with the cited codes and regulations to perform the installation.

•To install the heater in accordance with the clearances to combustibles.

•To furnish all needed materials not furnished as standard equipment.

•To plan location of supports, vents and air intakes.

•To provide access for servicing.

•To provide the owner with a copy of this Installation, Operation and Service Manual.

•To never use heater as support for a ladder or other access equipment and never hang or suspend anything from heater.

•To ensure there is adequate air circulation around the heater and to supply air for combustion, ventilation and distribution in accordance with local codes.

2.1 Wall Tag

A laminated wall tag is included with the heater as a permanent reminder of the safety instructions and the importance of the required clearances to combustibles. Affix the tag by peeling off the backing of the adhesive strips on the rear surface and position the tag on a wall near the heater.

A copy of the wall tag (P/N 91040031) is illustrated on the back cover.

Know your model number. Model number is found on the heater and in the Installation, Operation and Service Manual. See Page 9, Figure 3 through Page 14, Figure 9.

2.2 Corrosive Chemicals

CAUTION

Do not use heater in an area containing corrosive chemicals.

Avoid the use of corrosive chemicals to ensure a longer life of the burner, heat exchanger and other parts.

Failure to follow these instructions can result in property damage.

Roberts-Gordon cannot be responsible for ensuring that all appropriate safety measures are undertaken prior to installation; this is entirely the responsibility of the installer. It is essential that the contractor, the sub-contractor, or the owner identifies the presence of combustible materials, corrosive chemicals or halogenated hydrocarbons* anywhere in the premises.

*Halogenated Hydrocarbons are a family of chemical compounds characterized by the presence of halogen ele- ments (fluorine, chlorine, bromine, etc.). These compounds are frequently used in refrigerants, cleaning agents, solvents, etc. If these compounds enter the air supply of the burner, the life span of the heater components will be greatly reduced. An out- side air supply must be provided to the burners whenever the presence of these compounds is suspected. Warranty will be invalid if the heater is exposed to halogenated hydrocarbons.

2.3 National Standards and Applicable Codes

All appliances must be installed in accordance with the latest revision of the applicable standards and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in public garages, aircraft hangars, etc. may be applicable.
