PLEASE NOTE: The spi got s izes provid ed above are unit co nnectio n details only. The duct sizes required for th e discharge and return air should be selected as per the product sizing guide recommendations to achieve best air flows.
GENERAL The heater will operate at its optimum with a correctly designed, efficient ducting system. Avoid over-sizing the heater. The best and most economical central heating is obtained by selecting the correct sized unit for the job. Over sizing can shorten the life of the heater, create stratification and increase noise levels and running costs. The following points all have some effect on the total system efficiency. •
Ensure that a door, movable partition, furniture, curtain or other items cannot block the return air grille.
•
The return air grille must be sized to accept the full air capacity of the system at low noise level. Refer to product sizing guide.
•
Do not place the return air grille in a location where the returning air is drawn over people.
•
Warm air flowing from the outlets in each room must be able to return freely back to the return air grille. This is achieved by cutting 25mm from the bottom of each door or by fitting door relief grilles.
•
Where possible, the return air grille should be installed close to floor level for best system performance.
•
If a filter is to be fitted in the return air duct, it should be easily accessible for cleaning.

Ducting
DUCTING & DUCT FITTINGS •
Do not place an outlet register near the controller/thermostat as this can cause false readings
•
Do not place registers so that air is blown over people e.g. under tables, or a skirting register mounted horizontally under a sink or wash basin
•
To avoid exceeding maximum allowable air pressure drop in ducted system, do not use excessive lengths of duct. If a duct run exceeds 6 metres always install the next size larger ductwork. Note:
Duct register in small rooms with partially closed baffles to limit airflow mu st be consi dered as half a register.
•
Flexible ductwork must be run as straight as possible between the heater outlet and warm air outlets. Make sure there is at least 1500mm of straight ducting at the heater outlet.
•
The airflow through each outlet must be individually set to air balance the system.
•
The maximum discharge air temperature should not exceed 60-65C at 300mm from the unit discharge with the room at normal operating temperature.
•
Use a minimum of one outlet in every average sized room. A second outlet will be required for unusually large rooms or a bedroom with ensuite.
•
Refer to product sizing guide for the ductwork sizing guide.
•
All ductwork should be streamlined avoiding sharp angles that will reduce airflow.
•
Ensure all ductwork is taped airtight so that there is no leakage.
•
Balancing dampers maybe required to ensure even air distribution.
•
Always install damper blades in the branch take off fittings.
•
Ensure that the final ductwork bend to each ceiling register is a smooth radius so that the airflow is even from the register into the room. The minimum radius bend is 1.5 times the duct diameter.
•
Do not squash ductwork to fit through opening, as airflow will be restricted. Find a better location.
•
If more than 6m of flexible ductwork is required in one length, the next available size flexible duct must be used.

Setting the burner pressure is done in 2 parts. The high pressure must always be set before the low pressure can be correctly established. When adjusting either maximum or minimum gas rate, ensure the adjuster not being set is secured e.g. when adjusting the maximum gas rate, use a screwdriver to hold the minimum gas rate adjuster from moving. Setting the Maximum Burner Pressure 1. To adjust the maximum burner pressure, use a spanner on the hexagon nut and adjust in small increments. 2. Screw the adjuster clockwise to increase pressure, anti-clockwise to decrease burner pressure. 3. If the heater has been running for a while, the thermistor may be turning down the gas rate. To check the full gas rate, press down the pin in the middle of the minimum gas rate screw head. You will need something the diameter of a 1/8” rivet shank. Setting the Low Burner Pressure 1. To check and or set the minimum gas rate, remove one of the black gas modulating leads from the gas valve. 2. Adjust the gas rate in small increments using a Philips head screw. 3. Once checked replace the black gas modulating lead onto the valve. RETIGHTEN TEST POINT SCREW AND CHECK FOR GAS LEAKS. Installation Instructions - 2006

Commissioning Burner Pressure Setting the burner pressure is done in 2 parts. The high pressure must always be set before the low pressure can be correctly established. High Burner Pressure To set the high burner pressure correctly, the combustion fan must be set to run on maximum RPM so that modulation can not take effect.
1. Remove the pressure test point screw. 2. Place the manometer tube on the gas inlet pressure test point 3. To set the combustion fan to high speed shift the wire on CFAN on the Series3 modulating control board to a spare neutral terminal 4. To adjust the burner pressure, remove the plastic cover from the adjustment screw on top of the gas valve diaphragm. A small blade screw driver is required to adjust the pressure. Do not make large adjustments 5. Set the burner pressure as per the specifications laid out on the unit rating label 6. Return the combustion fan wire back to CFAN 7. Leave the manometer in place to check low pressure.
Installation Instructions - 2006
Page 49
HE EXTERNAL - NG & LPG
Commissioning Setting the Low Burner Pressure Setting the low burner pressure must only be set after the high burner pressure has been verified. The low burner pressure is set by adjusting the low speed modulation of the combustion fan.
To set the low burner pressure: 1. Ensure the combustion fan wire has been returned from neutral to CFAN. 2. Unplug the thermistor wire from the modulating control board. 3. Using a Phillips head screwdriver, adjust the low gas rate pot on the modulating control board. This will require movements in very small increments 4. Adjust the low burner pressure as set out on the gas rating label. 5. Replace the thermistor wire to the modulating control board 6. Remove the manometer, replace pressure test point screw and check for leaks.
CHECKING THE SYSTEM PERFORMANCE Once the gas pressure has been set, check the air discharge temperature in the duct to confirm the correct operation of the central heater. To test the correct operation of the heater: 1. Set room air fan speed best suited to the system. Replace electrical cover. 2. Check the temperature rise through the heater. The air temperature 300mm from the heater discharge should be between 60 to 65 0C at normal room temperature. Failure to comply will result in unsatisfactory performance of the heater. If this temperature is exceeded, check the ducting system for airflow restrictions and correct if necessary. If the temperature is still too high, increase the high fan speed setting. 3. Using the thermostat, switch the heater OFF. Wait for the room air fan to cease operation (approximately 80 seconds), then switch ON again to recheck the starting sequence. 4. Using the thermostat, switch the heater OFF unless the customer requires that it be left running. 5. Before leaving, make sure that the customer understands how to operate the heating system.
