Page 5: About Your Water Heater
ABOUT YOUR WATER HEATER MODEL TYPE Congratulations for choosing a Solahart electronic instantaneous gas booster water heater. The model you have chosen is for outdoor installation only and is only suitable for use with a solar water heater with an over temperature protection system. - Page 6 The power supply cord and plug must be replaced with a genuine replacement part available from Solahart. Phone your nearest Solahart Dealer to arrange for an inspection. The warranty can become void if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.

INSTALLATION – WATER HEATER THIS WATER HEATER IS FOR OUTDOOR INSTALLATION ONLY. THIS WATER HEATER IS NOT SUITABLE FOR USE WITH A SOLAR WATER HEATER WITHOUT AN OVER TEMPERATURE PROTECTION SYSTEM. THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING. Check the water heater is suitable for the gas type available. - Page 14 INSTALLATION – WATER HEATER As a guide the following requirements extracted from the Australian Gas Installations Standard AS 5601, must be observed. • At least 300 mm between the top of the water heater and the eaves. • At least 300 mm between the water heater and the edge of any opening into the building, measured horizontally along the wall.
- Page 15 INSTALLATION – WATER HEATER MAINS WATER SUPPLY Where the mains water supply pressure exceeds that shown in the table below, an approved pressure limiting valve is required and should be fitted prior to the solar storage tank. The solar storage tank may have a lower mains supply pressure requirement, which would govern the maximum supply pressure to the system.
- Page 16 10°C. In addition, a temperature limiting device capable of receiving a hot water supply temperature of up to 99°C should be used in conjunction with a Solahart thermosiphon closed circuit system installed without a HartStat over temperature protection system or a Solahart thermosiphon open circuit system.

- Page 18 INSTALLATION – WATER HEATER CIRCULATED HOT WATER FLOW AND RETURN SYSTEM A Solahart gas booster water heater cannot be installed as part of a circulated hot water flow and return system in a building. If a circulated flow and return system is required, it is necessary to bypass the gas booster water heater and install a secondary water heater connected to the hot water flow and return line and supplied from the gas booster water heater.
- Page 19 INSTALLATION – WATER HEATER REDUCING HEAT LOSSES The hot water line from the gas booster water heater and the pipe work between the solar storage tank and the gas booster water heater must be insulated in accordance with the requirements of AS/NZS 3500.4.

CONNECTIONS – PLUMBING CONNECTION SIZES Hot water connection R¾/20 Cold water (solar preheat) connection R¾/20 Gas inlet R¾/20 All plumbing work must be carried out by a qualified person and in accordance with the Standard AS/NZS 3500.4 and local authority requirements. All gas work must be carried out by a qualified person. - Page 24 CONNECTIONS – PLUMBING PIPE SIZES To achieve true mains pressure operation, the solar preheat water line to the water heater should be the same size or bigger than the hot water line from the water heater. The minimum recommended solar preheat pipe and hot pipe size is DN20. The pipe sizing for hot water supply systems should be carried out by persons competent to do so, choosing the most suitable pipe size to ensure adequate flow for each individual application.

CONNECTIONS – ELECTRICAL All electrical work and permanent wiring must be carried out by a qualified person and in accordance with the Wiring Rules AS/NZS 3000 and local authority requirements. Warning: Temperature controllers must not be fitted to this water heater as part of a solar water heater system because water at a temperature much higher than the controller setting can be delivered. -
Page 26: Multiple Installations
MULTIPLE INSTALLATIONS A multiple installation of Solahart 26 litre gas booster water heaters on a single manifold is possible, ® using the Equa-Flow manifold system, where large volumes of hot water are required. The Equa-Flow principle will function with water heaters in line, around a corner or in rows back to back. A recirculated flow and return system cannot be used. - Page 27 MULTIPLE INSTALLATIONS PRESSURE REDUCING VALVE COMMISSIONING PROCEDURE The pressure reducing valves must be set and commissioned for the gas booster. This procedure can be conducted with either cold water or solar preheated water, however the temperature of the solar preheated water must not exceed 58°C. To set and commission the pressure reducing valves: The gas booster water heaters are to be set to turn on and off in the following manner: The gas booster installation should be sized to cater for the cold water temperature in winter...

Page 30: Commissioning
COMMISSIONING All water heaters are tested and adjusted before dispatch from the factory, however further adjustments may become necessary because of local conditions. It is necessary to check and if required adjust the preset outlet temperature of the water heater. PRESET OUTLET TEMPERATURE The preset outlet temperature of the gas booster water heater must be set at 60°C for the system to operate correctly. - Page 31 COMMISSIONING Note: If this water heater is installed as part of a multiple installation, i.e. in a bank of water heaters, it will be necessary to isolate the other water heaters and commission the water heaters one at a time. However, all the water heaters will need to be operating during the checking of the gas pressure.
- Page 32 COMMISSIONING BURNER GAS PRESSURE It is necessary to check the burner gas pressure at both the minimum and maximum operational settings. It is necessary to have the electrical supply to the water heater switched on, the hot water must be flowing and the burners on to check and if necessary adjust the operational gas pressures. Warning: The removal of the front cover will expose 240 V wiring.
- Page 33 COMMISSIONING Notes: • If the burners extinguish and / or an error code starts to flash on the display, release the MIN and adjuster buttons, close the hot tap, clear the error code, turn on the water heater and recommence the procedure from Step 1.
