Restrictors - Valor PORTRAIT 530IN Installation Manual

Venting
Install Air Restrictors—Appliances with Vertical Vent Rise Only
No restrictors are required for appliances which only have a horizontal vent run.
If installing an appliance which has a rear vent facing outlet connection and no
vertical vent pipe rise, ignore this stage.
Two restrictor sets, like the one shown at right, are supplied with each 530
appliance. The restrictors cover part of the inlet air openings in the firebox
rear wall on each side of the brick support. DO NOT install the restrictors
in the roof of the firebox!
Each restrictor set includes an adjustable piece which can be moved to
different positions depending of the vent configuration. See the table below
to find out which position is optimal for each type of installation.
• To fi t the restrictors, loosen the two center screws of the left and right inlet
ports. Place the restrictor assembly under the screw heads and tighten the
center screws.
• To set the adjustable restrictor piece, loosen the two screws, position the
adjustable piece according to the diagram below and tighten the screws.
