• Top Cover and 3 fixing rails;
• Bend 90° ∅150 for combustion air;
• Flue kit (Comprising 1 bend 90° ∅100 + 1 terminal
1 flue flashing 1 blanking screw for combustion
sample point);
• New data plate
• Assembly instructions to remain with product.
EXTERNAL INSTALLATION
Installation of top cover.
Heaters types 1-2-3 are supplied with a single sheet
top cover (1).
Heaters types 4-5-6 are supplied with the cover (1)
comprising of two parts which should be assembled
prior to installation on to the heater.
Place the two pieces side by side and secure with self
tapping screws, seal the join with silicone sealant
To install the top cover remove the four self tapping
screws in the top panel and use them to fix the angle
brackets (2) (small) to the heater, remove the self
tapping screws at the rear of the fan housing and use
them to the rear bracket (3) (large) to the rear of the
heater .
Place the top cover (1) in position and secure with the
self tapping screws provided

4
EXHAUST EVACUATION AND HOT AIR INTAKE
Fitting flue terminal
Fit the 100 mm by 900 degree bend (4) to the flue spigot
on the heater;
Secure the fixing bracket (6) to the top with self tapping
screws;
Fit the flexible seal (2) to the top cover;
Before fitting the wind weather cowl to the heater it is
advisable to fit the combustion sample point (5) in the
pipe as shown in the diagram below;
Fit the wind weather cowl through the seal onto the flue
bend (4);
And secure in place to bracket (6) with a self tapping
screw.
Fitting combustion air pipe
Fit the 900combustion air bend 3 to the heater with the
air intake pointing downwards in order to help prevent
any water ingress into the combustion air intake
