To install the flue connection to the SHW85-435CE, SHW115-435CE & SHW145-435CE water heaters the
following procedure should be followed:
1.
Insert the exhaust transition (Item 5 in Figure 8.4) into the exhaust port on the heater.
2.
Insert the flue temperature sensor (supplied with the water heater) into the location hole on the exhaust
transition.
NOTE:
IF THE FLUE TEMPERATURE SENSOR IS NOT FITTED, THE FLUE GAS MAY EXCEED THE
MAXIMUM TEMPERATURE RATING OF THE FLUE AND CAN LEAD TO SEVERE PERSONAL INJURY,
DEATH OR SUBSTANTIAL PROPERTY DAMAGE.
3.
To the bottom (exhaust) connection of the concentric adaptor (Item 2 in Figure 8.4) fit one of the 100mm
dia. x 500 lengths (Item 3) followed by one of the 90 elbows (Item 4).
4.
Offer the assembly to the heater, ensuring the concentric adaptor is vertical, and measure the distance
between the centre of the air intake connection and the concentric adaptor. (See Figure 8.5)
5.
Remove the 100mm dia. x 500mm length and cut the measured distance from the plain end. (See
Figure 8.5)
6.
Insert the air intake transition (Item 7 in Figure 8.4) into the intake connection (Item 6) and tighten the
worm drive clip.
7.
To the side (intake) connection of the concentric adaptor, fit one of the 100mm dia. x 500mm length
followed by one of the 90 elbows.
8.
To the air intake transition, fit the final 90 elbow followed by the final 100mm dia. x 500mm length.
Measure and cut the 100mm dia. x 500mm lengths to suit the installation.
9.
Reassemble and fit to the heater.
10. Fit the flue gas test point (Item 1 in Figure 8.4) and clamp using its locking band.
