Installation, Service and Annual Inspection of the DualAir® unit 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 DualAir® unit is designed for heating and cooling non-residential indoor spaces. Do not install in residential spaces.

2.1 Clearances to Combustibles

In all situations, clearances to combustibles must be maintained. Caution must be used when running the DualAir® unit near combustible materials such as wood, paper, rubber, etc. A wall tag 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 DualAir® unit.

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 DualAir® unit components will be greatly reduced. Warranty will be invalid if the heater is exposed to halogenated hydrocar- bons.

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, refrigerant and venting installation. Note:

Additional standards for installations in Public Garages, Aircraft Hangars, etc. may be applicable.
