A. Installation Inspection

1. Follow safety inspection procedures recommended by

national, provincial, and/or local codes.

2. Be certain all electrical connections are properly made

and secure.

3. Visually inspect the vent system and determine that

there is no ﬂ ue gas spillage, blockage or restriction,

leakage, corrosion or other unsafe deﬁ ciencies.

4. Place the ﬁ replace in operation and determine that the

burner and power vent are operating properly. The

main burner should show no signs of ﬂ oating, lifting, or

ﬂ ashbacks.

B. Vacuum Switch Orientation

The vacuum switch must be installed on a vertical plane

for proper function. If the PVI-SLP is mounted in a vertical

position, the vacuum switch needs to be moved from its

place in Figure 5.1 to the location shown in Figure 5.2. To

do this, loosen and remove the two nuts securing it to the

inside wall of the PVI-SLP. Move and secure the vacuum

switch onto the adjacent wall using the two bolts that are

sticking out of the surface. Be sure that the tube running

from the vacuum switch to the motor is not pinched closed.

Operating Instructions

C. Setting the PVI-SLP Bafﬂ e Adjustment

The PVI-SLP has a bafﬂ e adjustment which must be set

during the Installation Inspection. This bafﬂ e adjustment

is located alongside the motor. See Figure 5.3.

The bafﬂ e adjustment is measured using the holes on the

indicator bar of the PVI-SLP bafﬂ e. See Figure 5.4. This

bar raises as the bafﬂ e is opened and lowers as the bafﬂ e

is closed. When only one hole is showing, the bafﬂ e is

closed. When all three holes are visible, the bafﬂ e is all

the way open. DO NOT TRY TO FORCE IT OPEN ANY

FURTHER THAN 1/2 in.

When the power vent is located within ten feet of the ap-

pliance, there is no limit to the bafﬂ e adjustment. If the

power vent is located more than 40 feet from the appliance,

the ﬂ ue bafﬂ e must remain closed and cannot be adjusted.

See Table 3 for limitations to the bafﬂ e adjustment.

The need to adjust the bafﬂ e will depend upon vent run

conﬁ guration and burner ﬂ ame characteristics.

Next to the bolt used for bafﬂ e adjustment is an indicator bar.

• If the burner ﬂ ames are short, active, and jumping – turn

the bolt clockwise (open). Check the burner ﬂ ames and

adjust the bafﬂ e again as necessary until the ﬂ ames are

stable, strong, and steady.

• If the burner ﬂ ames are tall, lifting, ﬂ oating, and ghost-

like, the bafﬂ e is too open and MUST be closed (turn bolt

counter-clockwise).

• If the pilot continously sparks and does not become

steady, the baffle may need to be opened. The

requirements in table 3 must still be met.

CAUTION! Risk of electrical shock! DO NOT allow

120VAC wires to contact hot metal surfaces. Use sup-

plied wire ties to bundle wires away from ﬂ ue pipe, fan

housing and other metal surfaces.

CAUTION! Risk of overheating! The bafﬂ e must re-

main fully closed when using the PVI-SLP with the PRI-

MO models. See PRIMO Installation Manual for details

and PRIMO48/PRIMO48ST exception.
