Fortunately, one of the most common mistakes is also easily avoidable; setting the unit.
From access concerns to performance issues, there’s more to locating HVAC equipment than keeping the arrow on the ‘This End Up’ sticker pointing skyward.
There are three primary placement concerns, and they’re as easily to remember as SOS.
Placement and clearances must comply with all local and national codes.
- Minimum clearance in front of electrical access panels.
- Proper distance from flue gas outlets and sewer vent stacks to fresh air inlets.
- Proper distance from Electrical services and LP or Oil Tanks.
Follow the manufacturer’s specifications to ensure proper operation. What’s the worse that could happen if you don’t?
- Loss of capacity
- Nuisance lockouts
- Component failures
This is another “follow the manufacturer’s specification” one. Example: The instructions list 6 feet for left side clearance….you install it a foot and a half from a wall…the wall causes flue gas to recirculate into the burner section and condenser coils causing:
- The coil fins deteriorate and the heat exchanger corrodes requiring replacement.
- The coil and heat exchanger are five feet long; there’s no room to remove them.
- The manufacturer refuses warranty due to incorrect installation.
Next time you’re placing a piece of equipment, cover your backside and remember SOS.
