FLUE TERMINAL INSTALLATION
8.8.1
TYPE B
23
When the heater is installed as a Type B
23
appliance, the flue system should be installed in accordance with the flue
manufacturer’s specific instructions.
A kit of components to facilitate conventional fluing of the appliance is available from Lochinvar Limited.
1.
Insert the exhaust transition into the exhaust port of the heater.
2.
Insert the flue temperature sensor 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.
Insert the air intake into the intake connection and tighten the worm drive clip.
4.
Insert the air inlet grill into the air inlet transition.
8.8.2
TYPE C
13
When the heater is installed as a Type C
13
appliance, the flue system should be installed as follows:
1.
Determine the location of the flue terminal, taking into account minimum distances as detailed in
Figure 8.1
,
Table 8.1
and the relevant British Standards.
2.
Taking care to protect the appliance from debris and dust, drill a hole in the desired location. The diameter
of the hole should be no more than 10mm greater than the diameter of the air supply pipe of the terminal.
3.
Determine the required length of the terminal and cut as necessary.
NOTE:
When determining the required length for the flue terminal, the outer wall plate or rosette should be flush to
the wall. (See
Figure 8.7
)
NOTE:
Once cut; remove all burrs and sharp edges.
4.
Insert the terminal into the drilled hole. The terminal section should be installed level or with a fall to outside
(Max. 10mm per metre) to prevent the ingress of water.
NOTE:
When inserting the terminal, ensure the air intake section is at the bottom.
5.
Fill the void between the terminal and wall with water resistant sealant.
6.
Fit the wall plates or rosette using appropriate fixings.
7.
Fit the concentric adapter (EKW175CE – EKW235CE only) and clamp using its locking band.
8.
Install the remainder of the flue system working progressively away from the water heater supporting the
pipes as necessary.
