Part 3
- Balancing the System Vacuum
NOTE:
The Premier VS burner is a variable rate appliance. Vacuum Pump setting must be accurately adjusted
to ensure Burners are operating at the specified design input.
1.
Turn ON the Electrical Supply but NOT the Gas Supply (remains turned OFF).
2.
Allow the system to run without Burners operating.
3.
With a manometer check the vacuum at the End Vent Cap of the longest Branch. (Refer to Figure 48 for
manometer positioning details.)
4.
Adjust the Damper that is installed in the Tailpipe of the same Branch to obtain the vacuum readings
according to Table E below. (In Systems that are “Symmetrical” there will be only one Damper along the
Common Tailpipe.) The setting maybe 0.75 to +0.50 in. W.C. at this time. Mark the Damper
positions for future reference.
5.
Proceed similarly until each individual branch in the system is balanced / adjusted.
6.
Shut down the System.
7.
Turn ON the Gas Supply.
8.
Turn up the Thermostat(s) to start the System and let it run (with Burners operating) for at least 30 minutes.
9.
With a manometer check the vacuum at the End Vent Cap of the longest Branch. (Refer to Figure 48 for
manometer positioning details.)
10.
Adjust the Dampers again (
Caution: dampers are now hot adjust with caution
) as required to obtain the
vacuum readings 0.1 to -0.2 in. W.C. of the settings in Table E. The Burners in this Branch should
now be firing at the appropriate rate.
11.
Proceed similarly until each individual Branch in the System is balanced / re-adjusted.
12.
Mark the Damper position and lock in place when the System has been balanced. (Lock in place by putting
a screw through the handle to hold it against the Sleeve / Tube.)
13.
Turn the Thermostat(s) down again to shut off the System.
Note:
An End Vent Vacuum which is intermediate to (between) those shown will result in rates intermediate
and proportional to those which are listed.
Note:
Vacuum settings and rates apply regardless of the number of Burners being used in the System Branch.
Your System is now ready for use.
