Figure 3: BASE MOUNTING CRITERIA
SECTION 4. FLUE SYSTEM & COMBUSTION AIR SUPPLY
4.1 Flue systems must comply with the rules if force
and national and local regulations.
4.2 The products of combustion must be flued to
outdoor atmosphere. Common flues for more than
one appliance must NOT be used.
4.3 Combustion air should be taken from out-door
atmosphere, this improves the operational
efficiency of the heating system.
4.4 Flues and combustion air ducts where connected
to the air heater must incorporate a disconnect
section adjacent to the appliance to facilitate
removal of the venter assembly for servicing. The
flue system must therefore, be supported
independently.
4.5 Dimensions and allowances in suggested flueing
and combustion air intake arrangements are based
upon the use of smooth wall aluminium flue and
combustion air ducts and fittings.
4.6 Type C Appliances
4.6.1When using a concentric termination arrangement as
figure 4, then only an approved system using
Reznor specified components may be used. These
items are manufactured from seamless aluminium
with connection sockets fitted with silicone double
edged seals, thus assuring, if the components are
undamaged, leak free flue systems.
Important: This type of flue/Combustion air intake
system is regarded as an integral part of the air
heater therefore, departure from this method of
flueing is in breach of the EC Gas Appliance
Directive.
4.6.2 Distance between the appliance and the concentric
flue termination must not be greater than 9.0 m.
When calculating the total length the following
equivalent data must be taken into account:
1 elbow @ 45° = 1 m
1 elbow @ 90° = 1,5 m.
