SECTION 1: HEATING SYSTEM SAFETY
SECTION 1: HEATING SYSTEM 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 and pump must be done by a 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 heating system is designed for heating nonresidential indoor spaces. Do not install in residential spaces. These instructions, the layout drawing, local codes and ordinances, and applicable standards that apply to electrical wiring, venting, etc., must be thoroughly understood before proceeding with the installation.
Thin sheet metal parts, such as the various venting components, have sharp edges. To prevent injury, the use of work gloves is recommended.
Do not attempt to operate the pump until all steps of the installation have been accomplished.
1.1 Manpower Requirements
To prevent personal injury and damage to the pump, two persons will be required for installation.

EP-200 SERIES PUMP INSTALLATION, OPERATION AND SERVICE MANUAL
SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
•To install the pump 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 furnish all needed materials not furnished as standard equipment.
•To plan location of supports.
•To provide access to pump for servicing on all sides and for pump removal.
•To provide the owner with a copy of this installation, operation and service manual.
•To never use pump or pump platform as support for ladder or other access equipment and never hang or suspend anything from pump or pump platform.
•To safely and adequately install pump using materials with a minimal working load of 400 lb (181 kg).
2.1 Corrosive Chemicals
CAUTION
Do not use heater and pump in an area containing corrosive chemicals.
Avoid the use of corrosive chemicals to ensure a longer life of the pump, burner, tubing 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 elements (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 outside 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.
2.2 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.
SECTION 3: UNPACKING THE PUMP
3.1 Open Shipping Cartons
Open cartons and remove packing inserts. Carefully remove pump components from the cartons. Lift assembly by gripping metal pump frame. Two people are required (weight 112 lb, 51 kg). This pump has been tested prior to packing. The impeller was dynamically balanced before assembly and requires care in handling to avoid damage.
WARNING
Severe Injury Hazard
Install pump scroll and inlet assembly before operating high speed rotating impeller.
Keep hands, fingers and clothing away from inlet and outlet.
Install and operate equipment according to installation manual.
Failure to follow these instructions can result in death or severe injury.
