2.1 Clearances to Combustibles
A laminated wall tag is available for 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 (e.g.
thermostat or ROBERTS GORDON
®
Controller).
A copy of the wall tag (P/N 91040029) is illustrated
on the back cover. Know your model number and
installed configuration. Model number and installed
configuration are found on the burner and in the
Installation, Operation and Service Manual. Write
the largest clearance dimensions with permanent
ink according to your model number and
configuration in the open spaces on the tag.
2.2 Corrosive Chemicals
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
elements (fluorine, chlorine, bromine, etc.). These com-
pounds are frequently used in refrigerants, cleaning
agents, solvents, etc. If these compounds enter the air
supply of the burner, the lifespan of the heater compo-
nents will be greatly reduced. 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 applicable standards and local
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.
CAUTION
Product Damage Hazard
Do not use heater in area containing
corrosive chemicals.
Refer to appropriate Material Safety Data
Sheets (MSDS).
Failure to follow these instructions can result
in product damage.
