Width can vary with gas train configuration.

If the V9A packaged boiler must pass through a 36” doorway, please

specify.

**

Add 6-1/2” to dimension C when equipped with optional top outlet.

***

Varies slightly with burner and gas train configuration and with or without RTC.

1. Do not tilt. Exercise caution when lifting to avoid damage.

2. This boiler can be lifted by fork truck. Do not truck from front.

3. When lifting from rear, forks must extend beyond center of gravity and second skid

cross bar.

4. When lifting from side, forks must extend to opposite skid rail and straddle center

of gravity.

5. Cable spreader is to prevent jacket damage. Spreader width should equal B (width

of skid) + 12”. Adjust cable lengths to lift at approximate center of gravity per chart.

BOILER PIPING - HEATING APPLICATIONS

CONNECT SUPPLY AND RETURN PIPING TO

HEATING SYSTEM

Connect supply and return piping to heating system (see

Figures 26 through 32). Flow direction for hot water

boilers must be from the rear return out through the top

front supply. Steam boilers can pipe return to the front

as an alternate location. Some boiler sizes may require

the use of additional supply and return tappings. Check

Figure 24 and applicable piping diagram for the boiler

size you are installing.

WARNING

Failure to properly pipe boiler may result in

improper, unsafe system operation and void

manufacturer’s warranty.

DO NOT improperly pipe boiler.

WARNING

All steam and hot water pipes must have

clearances of at least 1/2” from all combustible

construction.

WARNING

A hot water boiler installed above radiation level

must be provided with a low water cutoff device

as part of the installation.

1. HOT WATER HEATING - This boiler must be

installed in strict accordance with this installation

manual Deviations from these installation

instructions may void manufacturer’s warranty.

WARNING

Continued boiler operation for prolonged periods

of time under conditions when temperature

differential across the system exceeds 40°F and/

or, return water temperature stays below 135°F,

may result in premature boiler failure due to flue

gas condensation and/or thermal shock.

a. If the boiler is used in connection with

refrigeration systems, boiler must be installed

with chilled medium piped in parallel with

heating boiler using appropriate valves to prevent

chilled medium from entering boiler. See Figure

35.

b. If the boiler is connected to heating coils

located in air handling units where they may be

exposed to refrigerated air, boiler piping must

be equipped with flow control valves to prevent

gravity circulation of boiler water during cooling

system operation.

c. Burnham Commercial recommends maintaining

temperature differential (drop) across the system

at 40°F or less, and return water temperature at

minimum of 135°F for optimum operation and

long-term reliability.
