Incorrectly-sized expansion tank
6. Clean and flush system when reinstalling a boiler.
NOTE: This boiler must be installed within the prescribed clearances. If local building codes require additional clearance, these codes
supersede HTP’s. It is recommended to make note of the boiler model and serial number before finalizing installation.
B. FLOORING
Assure that the floor and structure of the installation location are sufficient to support the full installed weight of the boiler, including
water content of the heat exchanger and related piping. Failure to ensure the floor and structure of the installation location are
structurally sound before installation of the boiler can result in structural failure, substantial property damage, severe personal injury, or
death.
This boiler is approved for installation on combustible flooring, but must never be installed on carpeting. Installing this boiler on
carpeting could result in fire, explosion, property damage, severe personal injury, or death.
C. LEVELING AND DIMENSIONS
NOTE: It is recommended that the boiler be installed on a 4 – 6” raised boiler pad, rated for the weight of the fully operational boiler and
related piping. If flooding is a concern, it is recommended to further elevate the boiler pad to prevent water from reaching the boiler.
Figure 1 - Leveling
In order for the condensate to properly flow out of the collection system, the area where you locate the boiler must be level. The boiler
comes equipped with leveling feet. Should you find the floor beneath the boiler is uneven, adjust the leveling feet with a wrench.
