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.
