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 follow-

ing 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.

SECTION 1: HEATING SYSTEM S AFETY

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.

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

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

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

Severe Injury Hazard

Install pump scr oll 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.
