approved safety or relief valve.
NOTICE
This water heater has a limited warranty, a copy of which is printed on the back o f this m anu al.
It is the respon sibility of the in stalling cont ractor to see th at all contro ls a re correctly installed
and are operating properly when the installation is complete.
II. Pre-Installation
Inspect shipment carefully for any sign of damage. All
equipment is carefully manufactured, inspected and
packed. Burnham Corporation's responsibility ceases
upon delivery of water heater to the carrier in good
condition. Any claim for damage or shortage in
shipment must be filed immediately against the carrier
by the consignee. No claims for variances or shortages
will be allowed by Manufacturer, unless presented
within sixty (60) days after receipt of equipment.
Installation must conform to the requirements of the
authority having jurisdiction. In the absence of such
requirements, installation must conform to National
Plumbing Code and National Electrical Code,
ANSI/NFPA No. 70, current edition.
present.
Consult Burnham for size recommendations for
installation with unusual water demand.
Refer to Table 3 for water heater performance
specifications.
2. Boiler DOE Heating Capacity The Alliance™
water heater will provide the rated performance
only if used in conjunction with a boiler with a
DOE heating capacity at least as much as the
minimum noted in Table 3. If the boiler has less
capacity, the output of the tank will be reduced. To
determine the approximate reduction in output from
the tank use the following formula:
IMPORTANT DECISIONS REQUIRED BEFORE
INSTALLATION:
A. Sizing
1. Alliance™ Model - Choose the Alliance™ model
based on the expected water usage of the building.
The average residence with one shower or more
will require a model AL40A or larger. The AL26A
should only be considered for residences with
minimal water demand or for commercial
application where showers are not present.
Factors which dramatically increase water demand
include high flow shower heads, whirlpool tubs,
and the use of multiple showers at the same time.
Upsize the tank size if any of these factors are
For example, what would the first hour rating be if
a model AL53A were installed with a boiler having
a DOE heating capacity of 120,000 BTU/h?
Increasing the boiler DOE heating capacity above
the values listed in Table 3 will not increase the
rating of the water heater.
3. Circulator Sizing - Refer to Table 3 for the
minimum flow rate through the water heater coil
and the corresponding pressure drop through the
coil. Calculate the pressure drop of all straight pipe
and fittings on the supply and return of the water
heater at the minimum flow rate. Add the piping/
fitting pressure drop to the pressure drop through
the water heater coil.
5
Select a circulator which will provide at least the
minimum flow rate at combined pressure drop.
B. System Zone Control The Alliance
heater must be installed as a zone separate from the
space heating system. The domestic hot water zone's
piping and circulator must be sized for a minimum
flow rate with all zones in use and a maximum flow
rate with only the water heater in use. For this reason,
the preferred method of zone control is with
circulators.
1. Circulators - With space heating zones using
circulators, the Alliance™ should be added as an
additional zone with a circulator.
2. Zone Valves - Select a valve with low pressure
drop to assure adequate flow through the water
heater.
3. Hybrid - The space heating zone can be zoned
using zone valves and Alliance™ zoned with a
circulator. Refer to Figures 3 and 5.

water
C. Domestic Hot Water Priority Two options are
available, Priority and Non-Priority.
during simultaneous space and domestic hot water
heating operations, depending on such factors as
boiler output, boiler over sizing, number of space
heating zones calling for heat and ratio of domestic
hot water load to space heating load.
D. Component Location
1. Alliance™ Location
When such a location cannot be avoided, a suitable
drain pan must be installed under the water heater.
The drain pan must be connected to a drain.
Adequate clearance from combustible materials and
for service must be provided.
1. Priority Demand for space heating is interrupted
or postponed until the domestic hot water demand
is satisfied. This option provides maximum delivery
of domestic hot water. Priority is recommended
when:
a. Boiler net output is 100,000 Btu per hour or
less, or
b. When boiler output required to satisfy domestic
hot water demand is at least 50% of the boiler
output required to satisfy space heating demand,
or
c. When an interruption in space heating can be
tolerated during a long domestic hot water draw.
The delay in space heating may not be noticed due
to the fast recovery time of the AllianceTM water
heater. Certain water heater system malfunctions
(such as domestic hot water zone circulator failure)
could delay space heating indefinitely.
When zoning with zone valves, priority can be
provided with a three-way valve. Carefully size the
valve for proper flow to all zones.
The AllianceTM is design certified for installation on
combustible flooring.
The Alliance™ may be installed in a closet or
alcove.
2. Boiler Location - Locate the boiler as close to the
Alliance™ as practical.
3. Fixture Locations - For fastest delivery of hot
water, place AllianceTM close to points of use.
E. Additional Recommended Components
2. Non-Priority Boiler output is divided between
space heating and domestic hot water heating.
Delivery of domestic hot water can be reduced
1. Shut-off Valves - Allows isolation of water heater
from domestic water system and/or boiler system
during service.
2. Unions - Allows water heater movement during
service if adequate clearance cannot be provided.
3. Vacuum Breaker - Protects water heater's tank
from possible collapse if a hot tank is allowed to
6
cool to room temperature, or if tank is drained
without opening a hot water faucet. A Watts
Model No. N36 is an appropriate vacuum relief
valve.
4. Thermal Expansion Tank If water heater is
installed in a closed water supply system, such as
one having a back-flow preventer in the cold water
line, provide thermal expansion control. Contact
the water supplier or local plumbing inspector for
additional information. An Amtrol Model ST-12 is
an appropriate diaphragm style thermal expansion
tank for most installations.
F. Removal of Existing Domestic Water
Heating System
1. External Tankless Heater - Disconnect from
boiler piping and domestic water system.
2. Tankless and Storage Heaters - Disconnect from
domestic water system. Heater does not need to be
removed from boiler. If left in place, do not plug
®
inlet and outlet tappings.
G. Water Quality Improper water quality will reduce
the expected life of the Alliance™ water heater. Hard
water, sediment, high or low water Ph, and high levels
of chlorides in the domestic water should be avoided.
Sediment and hard water will coat the water heater coil
surfaces and reduce the rating of the water heater and
may, eventually, cause a failure. High or low Ph and/
or high chloride concentrations will cause the stainless
steel water heater components to corrode and
eventually fail. A filter is strongly recommended
where sediment is present in the water. A water
softening system is recommended for areas with hard
water.
In areas where water quality is unknown, a water
quality test should be performed.
WARN I N G
Do not operate ALLIANCE™ water heater in areas where water Ph is above 8.0 or below 6.0,
and/or with chloride concentra tions g reater than 80 parts p er million (pp m). Bu rnham' s Standard
Warranty does not cover problems caused by improper water Ph or excessive levels of chlorides.
