Congratulations on your purchase of a MiniMax NT/TSI Low NOx high performance heating system. Proper

installation and service of your new heating system and correct chemical maintenance of the water will ensure years

of enjoyment. The MiniMax NT/TSI Low NOx is a compact, lightweight, efficient, induced-draft, gas fired high

performance pool and spa heater that can be directly connected to schedule 40 PVC pipe. The MiniMax NT/TSI

Low NOx, also comes equipped with the Pentair multifunction temperature controller which shows, at a glance, the

proper functioning of the heater. All MiniMax NT/TSI Low NOx heaters are designed with a hot-surface ignition

(HSI) which eliminates the need for a standing pilot. The MiniMax NT/TSI Low NOx requires an external power

source (120/240 VAC 60 Hz) to operate.

This instruction manual provides operating instructions, installation and service information for the MiniMax NT/TSI

Low NOx high performance heater. The information in this manual applies to the MiniMax NT/TSI Low NOx 200,

250, 300, and 400 natural gas models.

It is very important that the owner/installer read and understand the section covering installation instructions, and

recognize the local and state codes before installing the MiniMax NT/TSI Low NOx. History and experience has

shown that most heater damage is caused by improper installation practices.

GENERAL DESCRIPTION

The MiniMax NT/TSI Low NOx Pool and Spa Heater incorporates a special burner with an induced draft

combustion system. The heater series is available in 200,000/250,000/300,000 and 400,000 Btu/hr.

The MiniMax NT/TSI Low NOx heaters are design certified by CSA (Canadian Standards Association) as complying

with the latest edition of ANSI (American National Standard Institute) Z21.56 · CSA 4.7-M98 in the USA and

Canada for both indoor and outdoor installations.

The MiniMax NT/TSI series complies with the Low Nitrogen Oxides emission requirements of California, South

Coast Air Quality Management District (SCAQMD) Rule 1146.2, Ventura County Air Pollution Control District

(APCD) Rule 74.11.1 and Title 30 Texas Administrative Code (TAC), Chapter 177.465.

The MiniMax NT/TSI Low NOx is designed to operate both in stackless outdoor installations and indoors with

stack vent installations—the indoor installation may be made using Kit 460506 or 460507; see pages 6 and 20,

vertical vent pipe or with an approved side-wall vent.

CODE REQUIREMENTS

The installation must conform with local codes or in the absence of local codes with the latest

National Fuel Gas Code, ANSI Z223.1, and the latest edition of the National Electrical Code, NFPA 70.

Installation in Canada to be made in accordance with the latest CAN/CGA-B149.1 or .2 and

CSA C22.1 Canadian Electric Code, part 1.

CONSUMER INFORMATION AND SAFETY

4. Before entering the spa or hot tub, the user

should check the water temperature with an

accurate thermometer. Spa or hot tub

thermostats may err in regulating water

temperatures by as much as 4° F.

5. Persons with a medical history of heart disease,

circulatory problems, diabetes or blood pressure

problems should obtain their physician's advice

before using spas or hot tubs.

6. Persons taking medication which induce

drowsiness, such as tranquilizers, antihistamines

or anticoagulants should not use spas or hot

tubs.

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the

appliance. Do not use this heater if any part has been under water. Immediately call a qualified service

technician to inspect the heater and to replace any part of control system and gas control which has been

under water.

WARNING

The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous.

See below for water temperature guidelines before setting temperature.

Introduction

1. Spa or hot tub water temperatures should never

exceed 104° F. A temperature of 100° F. is

considered safe for a healthy adult. Special

caution is suggested for young children.

Prolonged immersion in hot water can induce

hyperthermia.

2. Drinking of alcoholic beverages before or

during spa or hot tub use can cause drowsiness

which could lead to unconsciousness and

subsequently result in drowning.

3. Pregnant women beware! Soaking in water

above 100° F. can cause fetal damage during the

first three months of pregnancy (resulting in the

birth of a brain-damaged or deformed child).

Pregnant women should stick to the 100° F.

maximum rule.

Installation (Electrical)

ELECTRICAL, for MiniMax NT/TSI Low NOx Heaters

Electrical Rating 60 Hz 120 / 240 Volts AC, single phase

NOTE

The MiniMax NT/TSI Low NOx heater is prewired for 240 volt AC connection using the “RED/BROWN” female connector and

the “WHITE” common male connector; see below, Figure 3. If you require the heater to be connected to 120 volts AC, remove

the “RED/BROWN” female connector from the “WHITE” common connector; now locate the “BLUE” female connector and

plug it into the “WHITE” common connector.

When connecting the home wiring to the “Line Terminal Block” inside the junction box, follow the polarity as shown below.

Connecting to 120 VAC, make sure that you connect the positive wire to the positive terminal (L), the neutral wire is

connected to the neutral terminal (N) and the ground is connected to the ground terminal (GND); see below, Figure 4.

NOTE

If any of the original wiring supplied with this heater must be replaced, installer must supply (No. 18 AWG, 600V, 105° C. U.L.

approved AWM low energy stranded) copper wire or it’s equivalent. Thermal fuse wiring must be replaced with 18 AWG, 600V,

150° C. temp. rating. Interconnecting wiring to appliance must conform to the National electrical Code or supersede local

(wiring) codes.

In Canada: wires must be CSA approved.

WARNING

The heater must be electrically grounded and bonded in accordance with local codes or, in the absence

of local codes, with the latest national electrical codes ANSI/NFPA No. 70.

In Canada: CSA standard C22.1 Canada Electrical Code Part 1 and/or local codes.

Always use crimp type connectors when connecting two wires.
