SAFETY

Always read and follow all warnings on water heater

safety decals and in the manual. If the Installation and Operation manual is missing, go to www.intellihot.com or contact Intellihot (877) 835-1705 for a replacement.

DANGER

Use this water heater at your own risk. The outlet

temperature of the Intellihot water heater is factory preset to 120°F (49°C). The temperature can only be changed by using the control panel on the front of the water heater.

Hot water temperature over 125°F (52°C) can cause severe burns instantly or death from scalding. Children, disabled, and elderly are at the highest risk of being scalded. Do not leave children or the inﬁ rm unsupervised. Check temperature of hot water before taking a shower

or bath. To control water temperature to a particular faucet, temperature limiting valves can be installed by your service professional.

WARNING

Do not store or use gasoline or other ﬂ ammable vapors and liquids in the vicinity of this or any other appliance. Flammable vapors can ignite and cause serious damage or injury.

This water heater is factory preset for NATURAL GAS.

For propane conversion, refer to the manual. Connecting the water heater to any other gas supply can result in property damage, serious injury, and even death.

Suitable for water (potable) heating and

space heating. The water heater MUST NOT be connected to any heating system or components previously used with a nonpotable water heating appliance.

Do not use toxic chemicals, such as used for boiler

treatment, in potable water space heating systems.

This appliance must be installed in accordance with

local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the CSA B149.1, Natural Gas and Propane Installation Code.

water heater.

The discharge from the temperature/pressure relief valve

should be directed to the ground or into a drain system which will prevent a burn hazard or property damage. The piping must not have a reducing coupling or other restriction in the discharge line. The discharge line must be installed to allow complete drainage of both the valve and line.

If the system requires water for space heating at

temperatures higher than required for other uses, a mixing valve must be installed to temper the water for those other uses in order to reduce scald hazard potential.

The pressure relief valve must not be removed or

plugged.

PREPARATION BEFORE INSTALLATION

Selecting an Installation Site

IMPORTANT When installing this water heater, follow all local

building codes and the current edition of the National Fuel Gas Code (ANSI Z223.1/NFPA 54) in the USA or National Gas and Propane Installation Code (CAN/CGA B149.1) in Canada, when installing this product.

1. Select an interior location for the installation. Each installation is unique; therefore, take the time to ﬁ nd the best location for the water heater.

a. Install the water heater near locations that use hot

water, such as bathroom, kitchen, or laundry room faucets.

b. Select a location that minimizes the length of the

water pipe.

c. If the distances are long or if the faucet or appliance

requires “instant” hot water, we recommend running a recirculation line back to the water heater from the furthest ﬁ xture. Insulate the hot water supply and recirculation lines.

d. Select a location away from foot trafﬁ c and away

from areas where dust, debris, chemical agents, or other combustible materials could accumulate.

e. Allow sufﬁ cient space for service and maintenance

access to all gas, water, and drain connections.

f. Make sure the location meets all building code

requirements.

IMPORTANT Reduce the maximum equivalent length by 5 feet

per 90° elbow and by 2 feet per 45° elbow. Intake and exhaust venting pipes have the same allowable lengths. Do not exceed these set limits.

EXAMPLE: A 3” vent line or fresh air intake line

(Model i200) with the six 90 degree elbows would

be limited to a length of 70 feet in a WZLQSLSH

FRQILJXUDWLRQ

3. Locate the unit close to a drain and near gas and water

connections.

The water heater produces a signiﬁ cant amount of condensate during normal operation and should be located near a suitable drain where damage from a possible leak will be minimal. Installing the water heater in a location without a drain will void the warranty and Intellihot will not be responsible for any resulting water damages that may occur as a result. For additional information, refer to the Install Condensate Drain section.

The water heater should be located in an area where leakage from the unit or water pipes will not result in damage to the area around the appliance or to lower ﬂ oors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the water heater. The pan must not restrict combustion air ﬂ ow.

g. Make sure the wall surface the water heater is

mounted onto will support the weight of the unit.

SAFETY INSTRUCTIONS

The Intellihot i200 and i250 water heaters weigh 90 lbs. The i200P and i250P weigh 98 lbs.

2. Minimize the distance that the exhaust gas vent and fresh air intake must travel to an exterior wall.

a. The exhaust vent outlet must not be located next to

a walkway, near sofﬁ t vents, crawl space vents, or other areas where condensate (water vapor) could cause damage or create a hazard.

b. The fresh air inlet vent must be located at least 12”

from the exhaust vent.

c. Contaminated or dirty air drawn into the intake

pipe can damage the water heater. The Intellihot warranty does not cover damage caused by airborne contaminants.

16 Intellihot Green Technologies, Inc.

www.intellihot.com (877-835-1705)

PREPARATION BEFORE INSTALLATION

4. Locate the water heater and all water pipes in an area where the ambient temperature always remains above freezing.

NOTICE

In cold climates, if there is a power failure, the unit’s freeze protection system will not operate, and can result in water freezing inside the heat exchanger.

To prevent damage to the water heater, turn OFF the gas supply and inlet water valve. Open the drain valve and completely drain the unit.

Damage caused by freezing water is not covered by the Intellihot warranty.

a. When the water heater is connected to an electrical

power supply, it will automatically prevent the water inside the unit from freezing.

b. The unit’s freeze protection system will not prevent

the water in surrounding pipes from freezing.

5. Select an appropriate location for the combustion air and exhaust pipes to exit the house. Use the diagram and chart on the next page to make this determination.

High Elevation Installations

For operation at elevations above ,00 feet, Intellihot model ratings should be reduced by 4% for each 1,000 feet above sea level.

This water heater has a built-in control to limit the exhaust temperature to 149°F (65°C). As a result, the Intellihot water heater can be vented with Schedule 40 PVC. If the incoming (or recirculation return) water temperature does not exceed 150°F (66°C), the exhaust temperature will not exceed 149°F (65°C).

However, if you set the water heater at a temperature above 150°F (66°C) and you are also incorporating either an external recirculation loop or a combination heating system, the exhaust temperature can exceed 149°F (65°C). In that case, you must use Schedule 0 CPVC or Approved Polypropylene in the USA or Type BH Special Gas Vent Class IIB (CPCV) or Class I,C (Polypropylene) that conforms to ULC-S636 in Canada.

MULTIPLE UNITS

Gas Valve Adjustments Section

All Intellihot water heaters are designed to connect multiple units together. Multiple units increase the volume of hot water and also ensures that hot water is always available, even if one unit is shut down due to maintenance.

Connecting several units together requires proper sizing of water and gas piping, as well as increased sizLQJ in

the intake and exhaust pipes. Up to ten water heaters can be connected (cascading)

together. Use the steps in this section along with the basic installation procedure for installing a single unit.

NOTE: (DFKXQLWVFDQEHVLQJOHYHQWHGRUMRLQHG WRJHWKHULQDFRPPRQYHQW

The water heaters will communicate, via the cable provided with the water heater, during normal operation:

• When demand for hot water is low, fewer units will operate.

• If one unit has an error code, the others will continue to operate.

• Changing the settings (temperature, time, etc.) on one unit changes settings on all the units.

• It is possible to shut one unit down for maintenance while the others continue to operate.

1. Connect all the units to a gas supply pipe. Make sure

the pipe is properly sized in accordance with the BTU draw and number of units being operated.
