Install Instructions

5
CAUTION
Do not drop boiler. Do not bump boiler jacket
against oor.
A. Move boiler to approximate installed position.
B. Remove crate.
1. Remove nails and staples from crate.
2. Remove four carriage bolts holding boiler to skid.
3. Remove boiler from skid using ¾ inch pipe rollers.
a. Roll boiler to rear of skid. Handle boiler jacket
carefully to avoid damage.
b. Lower rear of boiler to oor.
c. Tilt boiler, remove skid at front of boiler, and
lower front of boiler to oor. Do not drop boiler.
C. Move boiler to permanent location. When using special
base for installation on combustible oor:
III. Steam Piping and Trim
WARNING
Failure to properly pipe boiler may result in
improper operation and damage to boiler or
structure.
A. Design and install boiler and system piping to
prevent oxygen contamination of boiler water.
Oxygen contamination sources are system leaks
requiring addition of makeup water, ttings, and oxygen
permeable materials in distribution system. Eliminate
oxygen contamination by repairing system leaks,
repairing ttings, and using nonpermeable materials in
distribution system.
II. Unpack Boiler
Figure 3: Special Base Installation
B. Boiler equipped with McDonnell & Miller 67 Low
Water Cutoff Only. Assemble gauge glass and low
water cutoff as shown in Figure 5. Follow instructions
packed with low water cutoff.
1. Afx Blow-Down Card to Jacket Left Side Panel
adjacent to low water cutoff.
2. Provide blow-down discharge piping.
C. Remove Jacket Front Panel. Remove parts bag from
vestibule area.
D. Install Safety Valve in Tapping 'E'. See Figure 4. Use
¾ NPT x 3" nipple and ¾ elbow provided. Safety Valve
must be installed with spindle in vertical position.
1. Place base on oor with insulated surface facing
upward and part number facing forward.
2. Position base to provide minimum clearances to
combustible walls. See Figure 3. Secure in place.
3. Place boiler on base. Center boiler on base to
provide minimum clearances to combustible walls
and ceiling. See Figure 2.
NOTICE
Before using copper for steam piping, consider the following characteristics of copper piping:
1) High coefcient of thermal expansion can induce mechanical stresses and cause expansion/
contraction noises if not accounted for in the piping system design and installation,
2) High heat transfer rate (heat loss) of un-insulated copper piping must be included in the normal piping
and pickup factors used to size the boiler,
3) Soldering or brazing pastes and uxes that end up in the system can cause poor heat transfer, surging,
an unsteady water line and wet steam if not thoroughly removed during boil out procedure and,
4) Galvanic corrosion of the adjoining metal may occur due to dissimilar metals in certain water chemistries
if dielectric unions are not used.
