Table 1 - General Data
Note. Gas consumption is calculated using a
caloric value of 38.7 MJ/m3 (1038 Btu/ft3) gross
or 34.9 MJ/m3 (935 Btu/ft3) nett
To obtain the gas consumption at a different
caloric value:
a. For l/s - divide the gross heat input
(kW) by the gross C.V. of the gas (MJ/m3)
b. For ft3/h - divide the gross heat input (Btu/h)
by the gross C.V. of the gas (Btu/ft3)

Notes.
1. It is most important that the correct concentration of the water
treatment products is maintained in accordance with the
manufacturers’ instructions.
2. If the boiler is installed in an existing system any unsuitable
additives MUST be removed by thorough cleansing. BS
7593:2006 details the steps necessary to clean a domestic
heating system.
3. In hard water areas, treatment to prevent lime scale may be
necessary - however the use of articially softened water is
NOT permitted.
4. Under no circumstances should the boiler be red before the
system has been thoroughly ushed.

INSTALLATION
Ideal Logic +Combi - Installation and Servicing
Notes.
1. It is recommended that a support bracket is
tted for every 1 metre of extension pipe used
and a bracket should be used at every joint, to
ensure pipes are held at the correct angle.
If a slip joint coupling is to be used then a
bracket should be used to secure the collar.
2. When extension ‘D’ packs are used the ue
duct MUST be inclined at 1.5 degrees to the
horizontal to allow condensate to drain back
into the boiler and out through the condensate
drain.
3. If the B pack, or telescopic B pack only are
used, they may be mounted horizontally. The
1.5 degrees is taken care of by the inclination of
the ue within the air pipe.
4. Only use water as a lubricant during assembly.
