XCHANGER OPERATION BASED ON AIR CHANGES PER HOUR

This method of operation can be used to supplement or provide for guaranteed air change rates. Table 1 shows the constant Cubic

Feet Per Minute (CFM) of air necessary to produce the desired Air Change Per Hour rate (ACH), assuming natural infiltration of out-

side air at a rate of .10 ACH. Square footage is determined by calculating the finished living space of the house. Garages and crawl

space should not be included. The constant CFM figures shown assume that the living space has standard 8 foot ceilings.

1. Determine square footage of house living space on left hand column.

2. Pick desired air change rate from top row.

3. Locate intersection of these points to determine constant CFM that should be obtained to meet desired ACH.

The X

CHANGER

will provide 180 CFM with both fans and 90 CFM with one fan operating. Where the CFM delivery of the

XCHANGER

exceeds that listed in Table 1, a standard plug-in timer can be set so the XCHANGER

is cycled to obtain the

desired ACH or Tjernlund’s optional SCP speed control may be used.

EXAMPLE

3000 square feet of living space

.2 ACH desired ventilation rate equals 40 CFM

CHANGER

capacity of 90 CFM (with one fan running)

In this example the plug-in timer may be set so that the X

CHANGER

operates for one half hour straight each hour or two fifteen

minute periods each hour.

RECOMMENDED INSTALLATION LOCATION

The XCHANGER

may be mounted anywhere in the house. The best place to mount it is the basement through the rim joist on top of

the foundation wall.

WARNING: Do not exhaust air from mechanical room unless makeup air is also supplied or equipment in mechanical room is sealed

combustion. Carbon monoxide poisoning may result. Use the DT2-6 6” duct take-off kit so exhaust can be removed from

outside the mechanical room if necessary.

It is required that the X

CHANGER

be installed in a location where it will not be directed at the occupants. Do not discharge intake air

onto water pipes or other equipment which may be affected by temperature extremes.

Do not terminate adjacent to thermostat. Outside temperatures can disrupt normal thermostat operation.

Do not terminate within three feet from a barometric draft control or intake grille of a heating appliance.

XCHANGER HOOD TERMINATION CLEARANCES

Install XCHANGER

in accordance with BOCA national Mechanical Codes M-306.1 and M-306.1.1 as follows, (See Diagram A).

M-306.1 LOCATION: Outside air exhaust and intake openings shall be located a minimum of 10 feet (3048mm) from lot lines or build-

ings on the same lot. When openings front on a street or public way, the distance shall be measured to the centerline of the street or

public way.

M-306.1.1 INTAKE OPENINGS: Outside air intake openings shall be located a minimum of 10 feet (3048mm) from any hazard or

noxious contaminant such as vents, chimneys, plumbing vents, streets, alleys, parking lots and loading docks. When a source conta-

minant is located within 10 feet (3048mm) of an intake opening, such opening shall be located a minimum of 2 feet (610mm) below

the contaminant source.

IN ADDITION TO THESE CODES THE MANUFACTURER RECOMMENDS THAT:

• The X

CHANGER

hood should be a minimum of 1 foot above grade or anticipated snow line.

• The X

CHANGER

hood should be a minimum of 3 feet from an inside corner of the building.
