• Hose connection ends should be tightened with clamp
and no other tools should be used.
• Gas installation rules with use of LPG bottles and
industrial tanks should comply with local standards
and to be performed by expert installation teams and
certified by the company undertaking the construction.
In case of failing to fulfil these conditions, combi boiler
shall not be commissioned by Warmhaus Authorized
Services.
2. The discharge pipe should be run in a proprietary drain
pipe material e.g. PVC, PVC-U, ABS, PVC-C or PP.
3. Metal pipework is NOT suitable for use in condensate
discharge systems.
4. Any condensate discharge pipework external to the
building (or in an unheated part of it e.g. garage) must
be insulated to protect against frost.
5. In all cases discharge pipe must be installed to aid
disposal of the condensate. To reduce the risk of
condensate being trapped, as few bends and fittings
as possible should be used.
6. When discharging condensate into a soil stack or
waste pipe the effects of existing plumbing must be
considered. If soil pipes or waste pipes are subjected to
internal pressure fluctuations when WC’s are flushed or
sinks emptied then back-pressure may force water out
of the boiler trap and cause appliance lockout.
7. Condensate outlet shall not be modified or blocked, it
shall always be downwards.

2.2.9. Filling the siphon for Condensation Line
After hanging the boiler on the wall, electrical connections,
radiator lines, hot tap water connections and condensation
water drainage line are completed, condensation siphon
should be filled with water (Figure 9).
Condensation line tightness should be assured.
Prior to installation of the flue elbow fill the
siphon in the combi boiler by pouring 1 litre
water to the internal flue against the possibility of flue gas
leakage possibility at first start.
Slope of condensation water hose and line must always
be towards down.
Attentions For Condensate Drain:
FAILURE TO INSTALL THE CONDENSATE DISCHARGE
PIPEWORK CORRECTLY WILL AFFECT THE RELIABLE
OPERATION OF THE BOILER
1. Ensure the discharge of condensate complies with any
national or local regulations in force.

2.2.10. Installation at Partially Protected
Exteriors
Installation instructions:
This combi boiler can
be installed in partially protected exteriors. Partially
protected place means that the combi boiler is located
at places without direct exposure to atmospheric factors
and precipitations (rain, snow, etc.).
Frost protection:
Combi boiler is equipped with a
system that prevents frost by automatically activating the
pump and boiler when the internal water is lower than
5°C.
Frost protection function only depends on below given
conditions:
