Installation Instructions
Blocked Vent Safety Switch
Installation
Use approved vent material only.
1. Install the venting so as to achieve
the shortest possible way with
minimum elbows. If necessary,
rearrange existing water piping to
achieve closest chimney connection.
2. Horizontal runs must be supported by
appropriate means to prevent
sagging. Avoid long horizontal runs of
vent pipe. Horizontal runs should
have not less than ¼" rise per ft.
*1
from the boiler to the vent terminal.
Metal strapping must be used to
support horizontal runs every 4 ft.
3. Connect factory supplied vent pipe
adaptor
using either three equally spaced,
corrosion resistant, self-tapping
screws and high temperature
silicone, or equivalent means.
4. Connect chimney via a 18" / 457 mm
long field supplied, slightly inclined
intermediate section of venting. Flue
pipe outside ∅: 5".
5. Drill a ½" opening on the side of the
vent pipe approximately three times
the vent pipe diameter away from the
flue gas collar of the boiler for flue
gas analysis equipment.
6. Seal all flue pipe joints.
7. Viessmann recommends that any
non-insulated vent pipe is insulated
to reduce cooling of flue gas and
velocity noises.
