8. FLUE INSTRUCTIONS
NOTE: THIS APPLIANCE MUST ONLY BE INSTALLED WITH THE SUPPLIED ACCESSORIES AND TERMINAL.
8.1 FLUES
NOTE: The ECONOMAIRE 32/INTEJAN can be used with horizontal or vertical flue types C12 and C32. You
should also consult (or be familiar with) British Standards BS 5440 Pt. 1 Flues
8.1.1 All joints must be soundly sealed.
8.1.2 Sufficient support brackets must be used in order to support the total weight of the flue system.
8.1.3 The flue must conform with Building Regulations and British Gas Materials and Installations specification (3rd
edition) regarding clearance and shielding from combustible materials.
8.1.4 The horizontal flue length MUST NOT be less than 300mm plus 90˚ bend and MUST NOT exceed 12m
excluding terminal.
8.1.5 The total vertical flue length MUST NOT be less than 1m and MUST NOT exceed 12m excluding terminal.
8.1.6 Total length refers to the equivalent worked flue length and therefore includes bends and NOT the distance from
the heater to the flue terminal.
8.1.7 When calculating total flue length, reference MUST be made to the following ‘equivalent lengths’:
a) 90˚ bend = 2m
b) 45˚ bend = 1m
8.1.8 The maximum number of 90˚ bends that can be used is:
a) Horizontal = 4
b) Vertical = 4
8.1.9 If a ‘short flue’ is used, the factory fitted flue orifice MUST be left
in place (see figure 4).
8.1.10 ‘Short flue’ refers to a total flue length not exceeding:
a) Horizontal (plus 90˚ bend) = 0.8m
b) Vertical (including terminal) = 5m
8.1.11 Where the total flue length exceeds these lengths, the flue
orifice MUST be removed.
8.1.12 The heater is supplied with either a horizontal or vertical flue,
dependant upon your specification when ordering. Reference
should be made to Table 3 for extra flue/terminal components.
8.2 HORIZONTAL TERMINAL LOCATION
8.2.1 The terminal must be positioned on the outside of the building
and allow for the free passage of air across it at ALL times.
8.2.2 Avoid positions where the terminal is adjacent to
projections, particularly under a balcony or immediately
adjacent to a drain pipe.
8.2.3 The terminal position must ensure that combustion
products cannot enter the building in which the heater is
installed (or any adjacent building) through windows, doors
or by any others means.
8.2.4 Figure 3 shows recommended terminal positions
8.2.5 It is recommended that the flue is fitted so that the outer part is flush with the wall. However, where this is not the
case, the maximum protrusion of the outer part of the flue through the wall MUST NOT exceed 22mm (see figure 3)
8.2.5 If the heater is to be installed in a timber framed building you MUST consult British Gas publication “Guide for Gas
Installations in Timber Framed Housing DM2” or your local gas region.
8.2.6 Where the lowest part of the flue terminal is located less than 2 metres above the ground, a balcony, or above a flat
roof across which there is access, the terminal MUST be fitted with a Tower Flue Components type K3 guard (or
similar) such that the distance between the guard and the nearest part of the terminal is no less than 50mm.
8.2.7 Reference should be made to Table 3 for required terminal components and guard.
8.2.8 NOTE: TO ENSURE THAT RAINWATER CANNOT ENTER THE HEATER UNIT, THE FLUE MUST BE
INSTALLED WITH A SLIGHT FALL AWAY FROM THE HEATER.
8.3 VERTICAL TERMINAL LOCATION
8.3.1 The ECONOMAIRE 32/INTEJAN is designed to be used with a vertical flue where the installation of a horizontal
flue is either not possible or not desired.
8.3.2 Installation of a vertical flue can be on either a flat or pitched roof with a pitch angle of between 25˚ and 50˚.
8.3.3 The terminal MUST be positioned on the outside of the building and allow for the free passage of air across it at
ALL times.
8.3.4 Avoid positions where the terminal is adjacent to projections; particularly under a balcony.
8.3.5 The terminal position must ensure that combustion products cannot enter the building in which the heater is
installed (or any adjacent building) through windows, doors or by any other means.
8.3.6 Figure 3 shows recommended terminal positions.
8.3.7 Reference should be made to Table 3 for the required terminal components.
