Hi..you have right way going see below my code 

if you need display before the product name then put  like this 
 

{block name='page_header_container'}
    {block name='page_header'}
      <h1 class="h1 tt-producttitle" itemprop="name">
         {block name='page_title'}
            {if isset($product_manufacturer->id)}
                {$product_manufacturer->name} - {$product.name}
            {else}
                {$product.name}
            {/if}
        {/block}
      </h1>
    {/block}
{/block}

Thanks
