John Wood Power Vent (Non-ENERGY STAR qualified models) - Manual (Page 13)

11. Dry fit all vent pipes, elbows, connectors and fittings
before joining any parts with solvent cement. PARTS
MUST FIT WITHOUT STRESS OR BENDING OF ANY
SECTION and each connection must overlap a mini-
mum of 13mm (1/2 in.). Do not force fit any of the con-
nections. Use only the appropriate solvent cement.
Caution: Solvent cements may produce flammable vapours.
Use only in well-ventilated areas and keep away from all
sources of ignition.
12. For 50mm (2 in.) venting, install the properly sized
rodent screen into the 50mm (2 in.) outlet elbow and
secure with a small quantity of silicone sealant. Outlet
elbows for 76mm (3 in.) are supplied with a metal rodent
screen already installed.
13. Do not seal the vent piping to the wall until the venting
is properly connected to the blower assembly.
