Boiler installation
Logano G234X – 6 720 804 886 (2012/08)16
In Canada the regulations in accordance with CAN/CSA B 149.1 and 2
Installation Codes apply.
5.7.3 Installing the flue pipe
▶ Mount the flue pipe on the flue outlet of the draft hood.
▶ Mount the flue pipe (4) with corrosion-resistant sheet metal screws.
5.7.4 Connecting flue pipe
Use only flue pipes with a suitable diameter for the boiler.
Every horizontal section of the flue pipe must have a minimum rise of
¼ inches per foot (21 mm per m) towards the chimney. The flue pipe
must be securely fastened to prevent it from hanging. A suspension must
be installed at least every 5 feet (1.5 m). Fasten every connection with
at least three (3) corrosion-resistance sheet metal screws. The end
section of the flue pipe must connect to the inside of the chimney smoke
duct.
A minimum clearance of 6 inches (155 mm) is required between the flue
pipes and all flammable materials.
The flue pipe must not be reduced in size and venting must not be
prevented by the installation of additional components.
▶ Connect flue pipe to the chimney with the shortest possible length of
flue pipe.
5.7.5 Installation of vent damper
Only the vent damper supplied with the boiler must be used for venting
the boiler.
The position of the vent damper must be visible.
The back flow check must be at least 6 inches (155 mm) from all
flammable components.
The vent damper must be freely accessible for maintenance.
The vent damper must be open when the main burner of the boiler is
operating.
▶ Place flue gas adapter [3] on the pipe nipples of the draft diverter.
▶ Install pins in the hole of the vent baffle [1].
▶ Fasten flue baffle to the flue connector adapter with three (3)
corrosion-resistant self-tapping screws.

5.7.6 Installing electrical connection of vent damper
▶ Disconnect all electrical power to your heating system.
D Start up the heating system to be tested. Follow the instructions
for commissioning. Set the thermostat for continuous
operation.
E After the main gas burner has been operating for five minutes,
check the opening at the back flow check for drafts with a match
flame or a candle, or with the smoke of a cigarette, cigar or pipe.
F Check this way that all heating systems that remain connected
to the venting system have been checked as above to ensure
that the venting operates properly. Then place all doors,
windows, venting fans, exhaust system flaps, and all other gas
fired appliances back into their original state.
G Any incorrect status of the common venting system must be
corrected to ensure that the heating system complies with the
regulations of the National Fuel Gas Code, ANSI Z 223.1. If the
size of any component of the common venting system is
changed, the complete venting system must be resized to
comply with the relevant tables in Part 11 of the National Fuel
Gas Code, ANSI Z 223.1.
DANGER: Risk of fatal injury from escaping flue gases!
A draft hood that does not work properly can cause
dangerous flue gases to escape.
▶ Note that the draft hood check cannot be modified.
In Canada the vent damper must not be installed on a
propane-fired heating system with a electronic ignition
system.
DANGER: Risk of fatal injury from electric shock!
▶ Only qualified electricians are permitted to carry out
electrical work.
▶ Before opening the appliance, disconnect it from the
power supply by means of the emergency shutoff
switch or the relevant circuit breaker in the main fuse
board.
▶ Take measures to ensure that the heating system
cannot be switched on again unintentionally.
▶ Please observe all installation instructions.
DANGER: Fire hazard from hot boiler components!
Hot boiler components may damage electrical cables.
▶ Ensure that the electrical cables are not touching any
hot parts.
▶ Make sure that all cables are routed through the
conduits provided.
