The THI boiler is pre-set in the factory for natural
gas H (G20)
.
This boiler comprises all the necessary accessories
for the correct working of a water based central hea-
ting circuit specifically:
- one boiler comprising:
• a high performance double walled condensa-
tion exchanger,
- a pre-mixing burner, with stainless steel refracto-
ry grate,
- a variable speed 230 Volt fan controlled by the re-
gulator,
- a 230 Volt two way gas valve controlled by the air
pressure,
- electronic regulation which ensures power modu-
lation depending on the demands for heating or
DHW (LMU control unit),
- an outside sensor,
- an expansion vessel,
- a modulating pump PWM signal,
- a 3 bar safety-valve,
- a rear wall spacer,
OPTIONAL:
- Horizontal flue kit (C

) - (extensions, elbows etc.).
- Flue adapter (C
33
) allowing the boiler to be con-
nected to a vertical flue.
- Accessories for vertical connection of the boiler
(C
33
) - (terminal, extensions, elbows etc.).
- Adjustment as a function of the room temperature
(REG 73).
- 2nd heating circuit kit allowing the connection of
a secondary heating circuit (REG 125).
- 2nd heating circuit clip-in allowing the connection
of a secondary heating circuit.
- Clip-in LPB communication kit used for cascade
or multi-circuit installations (REG 130).
- Clip-in programmable relay kit allowing a secon-
dary pump to work in parallel (REG 127).
- Control unit ZHTi 46 (REG 129) controlling an ad-
ditional heating circuit.
- Control unit ZHTi 47 (REG 128) allowing cascade
management for two boilers.
- Selector valve kit for connecting THI..C/BS.
