10. When making gas-piping joints, use a sealing
compound resistant to the fuel gas serving the boiler.
11. The boiler gas train has been factory leak tested
however, fittings may loosen during shipment and
installation. After gas piping is completed and before
wiring installation is started, carefully check all piping
connections, (factory and field), for gas leaks. Use a soap
and water solution or combustible gas detector. A GAS-
Mate 0119 or equivalent is recommended.

ƒ Components Requiring Ventilation to the
Outdoors
The SKP25 regulating gas valve has independent certification
as a ventless regulator and does not require ventilation to
the outdoors. The port marked "AIR" on the actuator is not a
gas vent connection, connecting a vent line to this port may
cause operational issues.
An authority having jurisdiction (AHJ) may not permit the
use of a vent limiter on some or all components. If venting is
required, use the following general guidelines:
Drill an appropriately sized penetration for each vent
ƒ
line through the topmost panel on the rear of the boiler
cabinet (Figure 11). Do not install any vent lines through
removable latching panels. Properly seal around the
pipe with silicone to maintain a sealed cabinet and
ensure combustion air will not bypass the filter.

Each component must have a separate vent line to
ƒ
the outdoors. Vent lines must not be manifolded or
combined with any other vent or exhaust systems.
Start with the vent connection size and as soon as it is
ƒ
practical, increase the pipe size one diameter. For every
ten feet of vent, increase the pipe size one diameter.
Never reduce the vent size.
ƒ Protect the vent termination from debris, dust and
insects. Install the vent termination above the snow
line and point down to prevent ingress of water. The
termination must be a minium of 3 ft (0.9 m) from a
source of ignition.
When required,
run the vent
line(s) through
