Marey Replacement for Bosch 80VP, Bosch 38B and Bosch 330PN

The Marey Power Gas GA10 or GA10DP 10L tankless water heater is the closest possible replacement for Bosch's popular line of 80VP, 38B or the 330PN tankless water heaters.  These units come in either Natural Gas (NG) or Liquid Propane (LP).  The only difference of the Marey GA10 and the GA10DP is that the GA10DP has a small digital panel on the front that shows the temperature when the heater is in use.

Like these Bosch tankless water heaters, the Marey GA10 or GA10DP tankless water heater has no electric requirement and uses 4" double-walled galvanized B-Vent for its exhaust venting. The Marey GA10 or GA10DP is perfect for off-grid applications.

While the Bosch 80VP, 38B and 330PN tankless water heaters all had a standing pilot light, the Marey 10L 2.6 GPM unit uses two D-Cell batteries for its ignition source.

At 79,000 BTUs, the Marey GA10 or GA10DP is very close to the 78,000 BTU maximum input of the Bosch 80VP, 38B and 330PN water heaters.

Marey GA10 or GA10DP 10L 2.6 GPM Tankless Water Heater
If you are looking to replace your existing Bosch 80VP, 38B or 330PN tankless water heater and your current unit is vented vertically through the roof then the Marey GA10 or GA10DP will be a simple and straightforward replacement.

The Marey Power Gas GA10 or GA10DP must be vented vertically with 4" galvanized B vent and there is no sidewall power vent for these units.

The Marey GA10 or GA10DP will work with lower water pressures than the Bosch tankless water heaters; the Marey GA10 or GA10DP will run on a minimum of 10 PSI water pressure.

The Marey GA10 and GA10DP 10L tankless water heaters are approved for installation throughout the US (including California) and Canada.

Please call GlobalTowne at 888-726-9752 for further questions or to place an order.

Ignition System of the Marey Power Gas GA5L/GA10L/GA16L

The Marey Power Gas tankless water heaters use a battery ignition system to activate their Power Gas models.  There are 3 different sizes of the Marey Power Gas units and they are the GA5L unit, GA10L unit and the GA16L unit.  The Marey Power Gas units run off 2 - D Cell batteries.  The Power Gas units are activated through water flow which sends a signal to the batteries and then to the micro switch and activates the burners.  The Marey Power Gas units require no electrical power to operate.  The battery box is located on the bottom right hand side of the unit and is easily accessible.

Marey Power Gas GA5L/10L/16L Tankless Water Heaters at Elevation

The Marey Power Gas naturally drafting gas tankless water heaters model GA5L/GA10L/GA16L are good for up to 6,000 ft elevation.  There are many people running the units at even higher elevations and the units will still operate well.  The air and gas mix at higher elevations will cause sooting in the heater exchanger and flue exhaust so this wants to be checked periodically.  You have to be aware that you will also loose 4% of your heat rise for every 1,000 ft above sea level...  this is applicable to all gas appliances.

Venting Change for Marey Power Gas Models GA5L/10L/16L

GlobalTowne is an authorized distributor of the Marey gas and electric tankless water heaters.  Marey has recently updated their manual for the power gas GA5L/10L and 16L units.  The installation manual has been revised to show that the 5L/10L and 16L power gas units must be vented vertically up through the roof.  The minimum vertical vent height shall be no less than 6'. Sidewall venting on a naturally drafting unit is not permissible and is against the National Fuel Gas Code (NFGC).  Below is a diagram that shows the vertical venting and also the venting specifications for each unit. 

Venting Specifications for:
Marey Power Gas GA5L - Uses 4" diameter double walled galvanized type B-vent

Marey Power Gas GA10L - Uses 4" diameter double walled galvanized type B-vent

Marey Power Gas GA16L - Uses 5" diameter double walled galvanized type B-vent

Marey Gas Tankless Water Heater Deactivation Issue

This is to address the issue of deactivation in the Marey gas tankless water heaters in warmer climate areas such as S. California, Florida, Texas and Arizona.  Deactivation is an issue when the incoming cold water to the Marey gas tankless is warmer than normal and the unit produces hotter water than normal and then when trying to add cold water to regulate the temperature the unit shuts off and "deactivates".  Turning the hot water tap off and then back on would reignite the unit but then the user would be faced with the same situation.  There are a couple options for addressing this.

1.  The user would want to adjust the Marey gas tankless to the "summer" setting which will give the burner it's lowest BTU burn point.

2.  If the user has the unit set to the summer setting and is still experiencing hotter water than normal then they would want to increase flow.  Increasing flow by turning the flow control knob to its max flow will increase flow through the heater keeping the unit active and giving a little cooler water and the end user will not have to add in so much cold water to cool the water down.

For further instructions on how to combat deactivation in warmer climate please call Marey Technical Support at 855-627-3955.
