Sequence of Operations

The combustion fan will run for several seconds before ignition to purge the combustion chamber of any gas.

If the front burner fails to ignite the appliance will turn off and fault code 11 will be displayed. If the rear burner fails to ignite the appliance will turn off and make another attempt to ignite. If this second attempt fails, the appliance will automatically turn off and fault code 11 will be displayed. This may occur when using the appliance for the first time or if it has not been used for a while. Try operating the appliance again.

The appliance may make noises after ignition or extinction of the flame. This is normal and is due to the thermal expansion or contraction of its components.

If the ON/OFF or the STANDBY/ON button is pressed immediately after the flame has been extinguished, the appliance will delay ignition for about 1 minute.

The normal ignition sequence is as follows:

1. When the ON/OFF or the STANDBY/ON button is pressed the Operation Indicator LED will glow red and the combustion fan will rotate to purge the combustion chamber.

2. Electric ignitor operates.

3. Gas is allowed to flow to the pilot when a spark is sensed.

4. When the pilot flame is established gas will flow to the front burners and then to the rear burners.

5. When all burners are established the appliance will automatically maintain the temperature setting.

NOTE: The appliance will wait until the heat

exchanger is warmed up before discharging air. This ensures that any discharge air will be warm and not cold.

Operation Indicator

The remote control emits an infrared (IR) signal and must be aimed at the receiver located to the right of the warm air discharge louvers. The normal operating range is about 16 feet (4.9 m) with an angle of about 40 degrees to the horizontal. This range will vary depending on the position of the installation and the strength of the remote control batteries.

Signal transmissions are confirmed by

• a brief illumination of the Transmission Signal Indicator on the Remote Display

• a flash by the Remote Control Receiver to the right of the louvers

• a beep from the appliance

The remote control transmits information whenever a button is pressed except as follows:

• when the lock function is activated

• when setting the timers, timer information is

transmitted only when the “TIME SET” button is pressed

Location

This appliance has a cool outer casing that allows it to be installed in a recessed application consisting of combustible materials such as wood and plaster.

The location needs to have a level surface that allows the appliance to be rolled in or out of the enclosure.

If the surface is elevated and there is not enough room for it to be rolled out then a base and joists may be used as shown.

The appliance will have to be rolled out for maintenance. After installation do not place any permanent fixtures that would prevent pulling the appliance out for access. To pull the appliance completely out of the enclosure a minimum of 15 inches from the front panel would be needed.

Do not vent the exhaust into ‘natural draft’ flue pipes or a chimney flue.

The enclosure must be within these limits:

Enclosure Dimensions

Width (w) 33.8 in (860 mm)

Height (h) 26.0 - 26.2 in (660-665 mm)

Depth (d) 15.0 - 16.9 in (380-430 mm)

The front panel extends below the surface on which the appliance rests. Ensure that clearance is maintained in order to install the front panel.

Drilling Flue and Gas Supply Holes

Check for water and gas pipes as well as electric cables. Use the template supplied to mark the wall locations for the flue manifold and the gas supply. Drill the flue hole using a 3 1/2 inch (90 mm) drill.

For weatherboard walls, drill through the center of the weatherboard from the outside first and then through the plasterboard.

Flue Manifold Installation

1. Disassemble the Flue Manifold

The flue consists of 3 parts:

• sleeve

• inside connection

• terminal

Disassemble the flue manifold by first pulling out the inside connection. To remove the outer terminal pull and release the two internal ties and then pull out the outer terminal.

Clearance to combustibles for the sleeve and flanges is zero inches.

2. Assemble and Adjust the Sleeve Length

Measure wall thickness through previously drilled 3 1/2 inch (90 mm) hole.

Inside Connection

Sleeve

Terminal

The end of the sleeve should protrude 3/16 - 3/8 inch (5-10 mm) from the outside wall.

In the “A” vent kit there are 4 parts provided with which to assemble the sleeve. Use the table to determine which pieces to assemble.

In both the “A” and “B” vent kits, two parts are threaded for additional adjustment.

Adjust the sleeve length to wall thickness plus 3/16 - 3/8 inch (5-10 mm).

For wall thickness plus 3/16 - 3/8 in (5-10 mm) Assemble these parts (“A” Vent Kit)

3. Attach the sleeve

Attach to the inside wall using 3 screws arranging

the flange so that the marking “TOP” is at the top.

The flange is offset 2° to allow the condensate to

drain to the outside.

3 screws

4. Install the Terminal

Check that the terminal seal is in place. For

weatherboard or vinyl siding, add the second seal next to the terminal seal to compensate for the angle.

From the outside insert the terminal into the

sleeve with the marking “TOP” at the top. The left hand side locking tie should be marked “LEFT”.

sleeve should extend 3/16 - 3/8 in (5-10 mm)

Terminal seal

5. Lock the ties

Pulling hard on the left and right hand ties, clip

the ties over the notches inside the sleeve. You should be able to pull the ties 2 or 3 notches past the starting point. Cut the ties, leaving about 3/4 inch (20 mm) past the notch. Bend the ties back into the sleeve and parallel to the wall.

6. Attach Inside Connection Assembly

Push the assembly into the terminal tube.

Attach the inside connection with 3 screws. The

inside connection can still be turned if necessary.

Extension Kit Installation

If necessary, extension kits are available to extend the exhaust line and air line between the manifold and the appliance. The maximum extension allowed is shown in the table below and is based on the number of 90° elbows used. Vertical extensions are not allowed.

maximum vent length 7.2 ft (2.2 m) 6.5 ft (2.0 m) 5.9 ft (1.8 m)

no elbows 1 elbow 2 elbows

Clamps

Both the exhaust line and air intake hose are supported by clamps which are attached to the wall. A wall fixture can be used to offset the clamp from the wall. If the wall fixture is not used then use Screw A and the nut to attach the clamp to the wall.

The air line should always be underneath the exhaust line so that in case the air line sags it will not come into contact with the exhaust line.

Installing the Exhaust Line

The exhaust line is connected between the joint pipe at the rear of the heater and the exhaust port on the flue pipe.

Slope the exhaust line 3° to the outside so that any condensate will drain away from the appliance. The figures below show two examples of horizontal exhaust line extensions.

1. Attach the clamp with one screw to secure the

extension pipe to the flue manifold.

2. Use pipe stopper A to clamp the connections with

all other components.

3. Use pipe stopper B to fix the length on the

adjustable exhaust pipes. Do not extend these pipes beyond the red line.
