PART 2 - SECTION I -

INSTALLATION INSTRUCTIONS

Before commencing installation:

1. Read these instructions in full !

2. Check that the heater you have

been supplied is suitable for the type of

installation and the gas available. The gas

supply pressure must be between the

minimum and maximum shown on the

heater data plate.

GENERAL

These instructions are provided to ensure the

correct installation and operation of your

Raypak Swimming Pool Heater.

Should any questions arise regarding the

specifications, installation, operation or

servicing of this heater, we suggest that the

local representative or Raypak Customer

Service be consulted.

Raypak heaters utilise a finned copper tube

heat exchanger resulting in a low water content

and reduced "stand by" heat losses. Therefore

a circulator pump of sufficient capacity to

match the heater model must be installed in

the system.

Raypak heaters are fitted with Australian Gas

Association approved components and all

boilers in this range are designed to comply

to AG501.

Some models are designed for either indoor or

outdoor installation subject to the appropriate

indoor draft hood or outdoor stackless top

being fitted.

Check that the correct top for your installation

has been supplied.

INSTALLATION PROCEDURES

All electrical, gas piping, gas connection and

flueing of the heater must only be undertaken

by a properly authorised person. The

installation must comply with local gas, AG601-

2000 and electrical codes and/or statutory

body codes and regulations.

Raypak heaters must be installed in the

filtration system, in the pool return line,

downstream from the filter.

INSPECTION OF EQUIPMENT

Check the heater and associated equipment for any

damage and if so notify your local representative or

Raypak for any further instructions.

DO NOT INSTALL OR START UP ANY

RAYPAK SUPPLIED PRODUCT THAT HAS

BEEN DAMAGED, WITHOUT FIRST

CONSULTING RAYPAK, AS ANY DAMAGE

OR FAULTS CAUSED BY UNAUTHORISED

START UP MAY NOT BE COVERED BY

OUR WARRANTY.

HEATER LOCATION AND

CLEARANCES

The heater should be located so that any

possible water leaks will not cause damage to

any adjacent areas or structures.

When such locations cannot be avoided, it is

recommended that a suitable drain pan,

adequately drained, be installed under the heater.

This pan must not restrict combustion air flow.

The heater must be mounted on a level non-

combustible base such as a concrete slab,

concrete plinth, steel plate etc.

Raypak heaters and equipment must not be

installed on carpeting.

The front of the heater must not be obstructed

by any gas or water piping, electrical conduits,

trees, fences, or other equipment, etc.

COMBUSTION/VENTILATION

AIR

Indoor model heaters must only be installed in

a protective enclosure or properly constructed

plant room with adequate ventilation in

accordance with AG 601 - 2000 Gas

Installation Code.

Ventilation shall be via 2 permanent openings

directly to outside, one at an upper level and

one at low level.

The minimum free area provided by each vent

shall be as calculated by using the following

formula, unless otherwise stated in AG 601.

A =1.5 X T

Where A = Minimum free ventilation area (cm2)

T = Total hourly input of all appliances (Mj/h)

Note: The minimum dimension of any opening

shall be 6mm.

Please take the heater location into account

when locating the fresh air vents because any

excessive draft will cause flame disturbance

and probable pilot outage. In some cases

where excessive draft effects the burner, the

risk of major damage is high due to

incomplete combustion.

Installations which obtain air from a source

other than directly from outside must comply

to AG601.

Warning: Air supply to the heater room

must not be affected by mechanical

exhaust vents located in other parts of

the house or building, such as kitchen or

bathroom fans, spa blowers, etc.

Mechanical exhaust vents may create a negative

pressure in the heater room that can become a

hazard by asphyxiation, explosion or fire.

Caution: Do not store chemicals or flammable

materials in the same room or near this

heater. Do not use aerosols near this heater

whilst it is in operation.

FLUEING

The correct Draft hood must be fixed to the top

of the heater and connected to a properly

constructed flue, vented to the outside using

only approved fittings.

Reduction of the flue diameter or alteration to

the draft hood voids all warranty. Where

flueing may be difficult, please contact Raypak

for advice, we will have solutions, particularly

where a fan assisted flue may be the answer.

The weight of the flue must not rest on the

heater draft diverter, the flue must be self

supporting and be fitted with a disconnection

section (bolted sleeve) to enable the heater top

and draft diverter to be removed easily, for

servicing. Where practicable the flue should run

vertically. Lateral (raised above horizontal) is

acceptable but the run of a flue shall not

exceed 50% of total flue height and shall be

designed to rise not less than 20 mm per 1 m

run. The flue must be terminated with an

approved cowl.
