8.2.4 Pump Inlet Adapter for 100 mm (4") Tubing
Apply a bead of silicone sealant 316° C to the 150
mm inside of the reducer 150 mm x 100 mm. Mount
the reducer to the inlet of the pump scroll using the 3
- #10 self drilling screws provided. See Figure 17.
IMPORTANT: To prevent leakage of condensate, do
not install screws at the 6 o'clock position.
Mount the pump boot to the inlet reducer using the
band clamp provided. See Figure 17.
8.2.5 Pump Inlet for 150 mm Tubing
Attach 150 mm pump boot to the inlet See Figure
18, then See Page 30, Section 8.2.3.

8.3 Building Ventilation

The space containing the heaters must have a
permanent outside air vent with a minimum effective
2
area of 4.5 cm per kW of heat input. If mechanical
ventilation is employed, the minimum proven airflow
rate shall be 2.35 m 3 /h per kW of heat input.

8.4 Ventilation Requirements

Detailed recommendations for air supply are given
in the relevant National Standards. There must be
an adequate supply of air for both combustion and
general ventilation. Air vents should have negligible
resistance. Do not locate air vents where they can
be easily blocked or flooded, or adjacent to any flues
or extraction systems carrying flammable vapour.
