SECTION 1: HEATER SAFETY

Your Safety is Important to Us! This symbol is used throughout the manual to notify you of possible fire, electrical or burn hazards. Please pay special attention when reading and following the warnings in these sections.

Installation, service and annual inspection of heater must be done by a registered installer/contractor qualified in the installation and service of gas-fired heating equipment.

Read this manual carefully before installation, operation, or service of this equipment.

This heater is designed for heating non-residential indoor spaces. Do not install in residential spaces. These instructions, the layout drawing, local codes and ordinances, and applicable standards that apply to gas piping, electrical wiring, venting, etc. must be thoroughly understood before proceeding with the installation.

SECTION 2: INSTALLER RESPONSIBILITY

•To install the heater, as well as the gas and elec- trical supplies, in accordance with applicable specifications and codes. Roberts-Gordon recommends the installer contact a local building inspector, Fire Officer or insurance company for guidance.

•To use the information given in the manual together with the local and national codes to perform the installation.

•To install the heater in accordance with the Clearances to Combustibles of this heater.

•To furnish all needed materials not furnished

as standard equipment.

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

•To provide access to burners for servicing.

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

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

•To ensure that there is sufficient ventilation in the area to comply with the requirements of

all relevant local and national codes.

2.1 Clearances to Combustibles

In all situations, clearances to combustibles must be maintained. Caution must be used when running the heater near combustible materials such as wood, paper, rubber, etc. A wall tag (P/N 91040028) is on the back cover of this manual as a permanent reminder of the safety instructions and the importance of the required clearances to combustibles. Affix the tag on a wall near the heater.

2.2 Corrosive Chemicals

CAUTION

Do not use heater in an area containing corrosive chemicals.

Corrosive chemicals will damage the burner and heat exchanger 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 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.
